YEA. I've been having hives for 2 months now. After reading this post, I did a search on the internet and went last Friday (July 16, 2010) and bought for $3 a bottle of 500mg L-Lysine. I am taking one at a time on an empty stomach, three times daily. The Saturday I had practically no hives. The itching went away almost completely. Now, four days later, for the first time in two months, I feel something is working. They haven't disappeared completely, but I know I'm getting better every day. I didn't try antihistamine drugs that only mask the symptoms and are not good for the internal organs. I also ordered a blood cleanser on ebay, because I read that according to ayurveda, allergies are usually caused by blood impurities. Thank you for the advice.
