If one sore has emerged, then it goes away quickly - if it hasn’t then the L-Lysine makes it go away fast.
I keep a bottle of it in my vehicle, as we know those suckers can strike at any time & don’t wait until you have some on hand.
Reading through the posts, some take it daily. I heard you should ONLY take it when needed and prolonged use is not good for you, other posts say it can affect the liver-so be careful out there, do your research, and if confirmed, only take for a few days to a week.

Read about Vitamin D deficincy in The Star Tribune by a doctor at the U of MN who discovered how many people suffer from a lack of it. Of course, I am a blue eyed blond who frys like a lobster in the sun and can't remember when the last time was that I went outdoors without sunscreen and and hat so I began taking a D supplement right away. I take 2000 IU of vitamin D daily. I have to say that I feel pretty darn good considering I have arthritis in all the major joints of my body.
I also have been using lysine to take care of my Herpes simplex outbreaks for years and would not be without it. I find that if I take 4-6 500 mg tablets at the first sign of the itch/tingle on my lip, and then 2 tablets every couple of hours after that, I can most times, stop it in its tracks and completely skip and signs of the break out. If I am nowhere near my supply of lysine and I get those symptoms, taking it at first opportunity causes the leisons to heal very rapidly. In any case, it works for me.
Am going to try the apple cider vinegar thing as well, for arthritis and for the flea problem. Weird that it will be for 2 such unrelated problems but If it works, who cares. It is certainly safe enough. Thanks for being here as a sounding board and gathering of natural remedies.

L-lysine for cold sores WORKS!!!
My mom, sisters and I suffer from cold sores- or at least we used to, because we discovered that taking L-lysine stops, actually STOPS cold sores in their tracks. As soon as you feel that “is that a cold sore funny sore feeling “ on your lip or around lips area, start taking L-lysine immediately! Take 1000 mg of L-lysine two to three times a day. So immediately effective and we all carry in our purse and on trips so we have immediate help in case it strikes while you’re out and about. I’ve spent so much money or various cold sore lip creams but this is the best ever! L-lysine.

First of all, STRESS and DIET are the two main culprits of these sores. Any diet high in Arginine combined with unusually high levels of stress, little sleep, or menstration will definitely make it hard for the body to fight off cold sores. I have found that I MUST completely eliminate coffee, any form of nuts (including peanut butter), oatmeal, and soft drinks in order to prevent these suckers from appearing. Chocolate intake also needs to be monitored. All 4 times that I have gotten these sores, I had had unusually high levels of stress and had a ton of coffee/soft drinks. I don't know if it is the caffeine or coffee itself, but I do know this must be avoided altogether for me.
Taking L-Lysine each day is NOT suggested, since your body will become immune to it, and it won't be as effective taking it when a cold sore does appear. However, making sure to eat foods with Lysine everyday if you are a frequent sufferer is essential. Yogurt (with live cultures) is wonderful as far as lysine counts are concerned. I have started to include yogurt in my daily diet , and other dairy products such as cheeses and milk, since these are all wonderful foods rich in lysine. Also, most vegetables are excellent as well.
Despite all these precautions, sometimes the suckers still appear, and treatment is vital in getting rid of them quicker. I use a combination of abreva (as soon as it first appears), hand sanitizer (especially if the blister is very tiny... I will pop it and IMMEDIATELY apply hand sanitizer to kill the germs... And make sure to wash your hands thoroughly afterward.. This seems to be effective), as well as nail polish remover to dry it up. The bigger the sore gets however, the less you should touch it. Definitely do not pop it if it is huge, since this will only spread germs. The best method for a huge sore is to dry it out, so nail polish remover is best. Also application of honey, beeswax, and hot tea bags have all seemed to relieve it, though I am not sure if those actually HEAL the sore.
On top of these topical applications, I also take LARGE doses of lysine (about 1000 every few hours), as well as Vitamin C. I believe this is honestly the most crucial part of the whole treatment. Make sure your diet is completely free of arginine when the sore is developing... Otherwise it might get pretty nasty. Arginine is prevolent in coffee, chocolate, nuts, peanut butter, coconut, oatmeal, wheat (meaning bread and beer needs to be avoided!! ), jello, brown rice, beans, and lentils.
Eating a lot of licorice also has seemed to help me a ton(make sure the licorice you buy contains real licorice extract... the artificial stuff won't help).
This is a lot... But this is my method of prevention and treatment that seems to work quite nicely. Hope this helps someone!!
