For Herpes Simplex (HSV) "One day I got a severe headache. It lasted for 3 full days. I was tired, could barely move, pain all over. I developed a rash, almost like chafing on my inner thighs next to my lady parts. I knew it was herpes, so I went and got tested, and sure enough, it was positive for simplex 2. Being 25 and only having two partners really narrowed down where I got it from. I am still with the person who gave it to me. Anywho. I was prescribed generic Valtrex (acyclovir), it cleared up the rash in about a week. But it had harsh side effects: leg pain, stomach pain, etc. I researched lysine and began taking it after my 10 days of acyclovir. It has been 3 months and no further outbreak. I had my cycle and felt that viral tingle, I increased the lysine and no outbreak."

For Herpes Simplex (HSV) "Began taking 500-1000 mg twice daily to suppress a recurrent sore/bump on the rear side of my palate. This increased greatly in recurrence due to immunosuppressive drugs for another condition. The lysine seemed to work for about a week, but now is possibly causing frequent stomach/gut pain and cramps. Might stop lysine and see if stomach cramps resolve, then resume dosing at a lower level, maybe 250 mg 2X daily. I skipped a dose or two to see what would happen, and the mouth sore came right back. But I'm not sure the stomach cramps are tolerable, since I already have Crohn's with a lengthy stricture..."
