I just found this site and love it. I read all on MSM. I have been using it for over 10 yrs. I first heard of it when my Bullmastiff ripped a musle in his back leg completely in half. He could not use his back leg at all. After about 7-10 days on 1TBS of MSN a day he started using his leg a little at a time. When he began using his leg regularly I then just added a sprinkle to his water eveyday. In about 6months I noticed his eyes had cleared up. He was almost blind when I adopted him.
During this time I read everything I could about MSM and found that it does detox you among other things. If you read anything on detox you will find that it is important to go slow, after years of use of perscription drugs, and loads of other toxins we breath and eat every day it is not suprising to me that so many people had bad reactions. I also noticed that almost every one was still taking perscription drugs as well as MSM. Some of the side effects if not all of them sounded like basic detox results. You must slow down your detox. Your body was telling you it needed more water. Was it tap water? You should have several BM aday your body is purdging things out. If I were havig these side effects I would do more research on detox side effects and how to slow down and treat natually. For instance look at what happens to drug addicts. It can be life threatening! Remember more is not always better and education is the answer. I hope you all find the answers you are looking for.
Another thing to try- If you have a sick dog put MSM in a bowl about a tablespoon. Right next to his food. I use loose not caps. I have done this with healthy animals as well. But every single time the ill dog has lapped it up. I give it to all my animals birds, turtles, snakes, hedgehog, lizard, cat, dog,and tortis. Animals instinctivly know what they need. They have always taken it when offered. Good luck to all of you.
