I have been bathing in ACV for two days now and have noticed that little bumps between my lower butt and thighs are getting worse, like filling with puss (yuck) and everytime I do it I feel like I am getting a cold and my lungs feel how they do when you have cold in them and my nose feels like it wants to stop up and I sneeze I mean it feel like an instant cold, I am using regular acv from the drugstore because it is what I have on hand, I have also on the second day added baking soda. the bumps started coming when I was body brushing
oh the cold is gone by morning

Try unfiltered, organic, ACV (health food stores) ....you'll get a deliciously flavoured ACV that is pure and realiably 5% in acidity....the "knock-offs" are almost always impure and far more acidic.....I dilute 1- TBS ACV w/4oz. H20 & a pinch or two of baking soda (5-days on 2-days off)....or 2-TBS. w/8oz. H20 & 3 or four pinches of baking soda (4-days on 3-days off)...If you try this, start with the lower dose ...I think you'll thrive & find that previous problems wree caused by over-dosing,too much acidity and/or under buffering w/soda...(I've come to actually crave the ACV on off days, due to it's delicious taste w/o the multitude of health benefits it offers ...Good luck!

I love taking ACV, however one day I was going to shortcut. So I drank a big tablespoon down without dilution. this made my throat swell up to the point I couldn't breathe. Being at home by myself I quickly got the spray nozzle and started spraying out my mouth and throat. I thought I was goig to die. But spraying the water into to the mouth did the trick. After I could actually swallow again I gulped down water to further dilute it.

I have started using Apple cider vinegar one spoon twice daily since two days. I am a diabetic. I take metformin and actos low dose daily. I was struggling from bloating of late and after taking ACV I really felt relieved from bloating. But i feel tired and depressed all the time these two days and no interest in anything. Is anything wrong because of ACV?I would appreciate if I get some good thoughts on this issue.

Just started using ACV for acid reflux but I'm so tired since I started. Is this a side affect? When can I expect to have energy? Also by the way the ACV worked the first day for my acid reflux.

Hi. I am a new user of ACV and am very pleased and surprised at the way it is helped me to feel better. I know that I have always struggled with candidiasis, but never got the complete relief from it using other remedies. The ACV has made an incredible difference in how I feel. I have also experienced the other benefits of increased energy, decreased anxiety, better sleep. However, there is one concern I have that I hope someone can help me with. Sometimes when I take the ACV it seems to upset my stomach. Help! I really value this remedy, but I'm concerned about stomach upset. Thanks.

I feel I sleep better when taking ACV and since I have a problem with high blood pressure it is helpful in that regard also. I do have a problem though, whenever I take it for awhile, like 3 or 4 days I get constipated. Do you know why? Lately I have been taking it by itself, I don't like it with juice or water, however, I could go back to taking it that way.

ACV gives me heart burn the instant I drink it! Isnt it a aid in the reduction of heart burn and reflux? Help! Heart burning in CT
EC: Some brands of ACV are more acidic than others, even though they state 5% acidity on the bottle...

I am new to the ACV remedy. I want to take the ACV to lose 20 pounds. About 2 months ago, I started taking estrogen & progesterone. I have gained over 6 pounds in the mid-section. I stopped taking the hormones now. I am 52 years old. I have been taking ACV 3X/day, 2T ACV + 1/4t BS in 8 oz water for about 10 days. I take it before breakfast, after lunch & after dinner. I haven't lost any weight yet. But my blood pressure has gone up quite a bit from 113/72 (with BP medication) to 142/82 and starts getting headaches. Has anyone have the similar problem with ACV? Or am I doing something wrong? Thanks for your responds.

I was using ACV 2 tbsp in water 4 x day for 3 mon straight. Because of really bad vaginal itching I thought I should take a break. I stopped over the weekend, today is Tuesday, and my skin itches, I have pink eye, sore throat, sore neck, face breakouts--coincidence???? Any feedback?

I tried acv for a bladder infection. Because of the bad taste, I took 2 tsp. straight. Beware! I was nauseous for hours and my esphogus and tongue feel burnt! So much for a remedy- I will be heading to the doctor's for antiobiotics and now instead of one problem I now have two!

Have read with interest the articles on ACV and decided to try it. 3 days later and I have a mouth full of canker sores. Having good success healing them with alum, the pickling spice. No pain w/ application,but what did I do wrong? I'd like to continue with ACV as it has so many health benefits but can't live with mouth sores. Now what?

I am acidic. I took 2 TBSPS organic apple cider vinegar with the mother in it in a gallon of water. I did this for several days. I caused me to have a bleeding cystitis and had to take antibiotics. I did this to alkalize my body. Now i will try the baking and water only. Will let you know if i still develop bleeding cystitis. Melly

For the first time in my life I am experiencing something like the flu. The doctor does not know what it is--bacterial or viral. It has the same symptoms as my grand daughters illness two weeks ago. She like me, began with fever of 104 and body aches for a couple of days. No other symptoms. After receiving Antibiotics, she had to be rushed to the emergency with a serious allergic reaction. She had a very nasty rash and cough. It took her two weeks to recouperate. I took care of her after I spend a few weeks traveling and not taking care of my self. Two days after I returned home, I came down with the fever, chills, and diareahea. After reading about ACV decided to take a bath in it to help reduce fever and detox. Within an hour of the bath, I broke out in a rash with blisters and have had them for three days now along with the cough that keeps me up all night. I am now on antibiotics and Vitamine C and tring to rest. The burning itching of my skin is almost unbearable. I use prayer to get me through the waking hours. I am now resorting to benedryl to keep from scratchin. Does any one have any suggestions?

Have been using the ACV remedy for about 2 mos and notice the immediate difference in my skin and in my lack of joint pain (I suffer from Carpal Tunnel). However, I also started to notice that my skin was getting dry and I was constantly tired and kind of depressed. All symptoms that I had before I got my thyroid checked. I have hypothyroidism and take Levothyroxin once daily in the am. I had been starting my day with the thyroid pill, then my ACV tonic. WELL, I just read on the Medicine bottle to take this medicine at least 4 hours prior to any antacids, iron or vitamin/mineral suppliments. Basically, the ACV was just washing away my meds. So I adjusted my times and don't take the ACV til later and I'm back to my old self, with the added ACV bonus! SO, check you medicine labels!!!

Question for Ted: I find that drinking vinegar on a daily basis, even a small amount like 1 teaspoon, will cause insomnia that gradually increases nightly, but goes away when I quit drinking vinegar daily. I read a couple of comments from readers regarding vinegar causing insomnia, but no answers about whey this might be happening. Any thoughts to share?
