Funny you should ask, Shelly!! Really!! I was trying to loose some of this lovely weight that Lyme, menopause, and a faulty thyroid has left me with - soooooooo I get this bright idea that I can take things without double checking everything - HA!
I started taking L-arginine and couldn't figure out what was happening to me a couple of weeks later - then I came across an article while trying to research something for someone else that said L-arginine can reactivate EBV!!!
Oops!
So I stopped the L-arginine day before yesterday and started back on L-lysine at 1,000 mgs 3 times a day and today I feel human once again!! Woo Hoo!!
I've also used L-Lysine when I would go through a period of cold sores (which are caused by the Herpes virus as well), and it cleared them up faster than any other product that I've ever used......and I've used quite a few of them!
