For Herpes Simplex, Suppression "I never do reviews but I'm hoping this will help someone. I was diagnosed with Herpes Simplex Virus 1, orally and genitally, that I got from a loser who knew he had it but did not tell me. I recently had a genital outbreak and started taking L-Lysine as soon as I felt it coming. The blister did show up but started fading away and was almost gone after 4 days. I took about 3,000 of L-Lysine a day. I'm not sure of the recommended dose but I did not have any side effects. This stuff really does work for genital and oral herpes!"

For Herpes Simplex, Suppression "One day after starting the l lysine, I have horribly swollen lymph nodes on my underarms. It's been 3 days and they are still painful and swollen. I did have smoothies each a.m with mango and yogurt which I read are high in lysine as well. I am stopping use due to this reaction."

For Herpes Simplex, Suppression "I have IBS with alternating diarrhea and constipation. I tried L-Lysine a few months ago but thought it increased diarrhea and abdominal cramps. Continuing to break out I tried the Lysine again, routinely twice daily. Unfortunately, the diarrhea and abdominal cramps have returned and I'm stopping the Lysine immediately."
