For anyone following this thread: Come to the Facebook Aquagenic Pruritis Support Group! Also do some research on an amino acid called beta Alanine. It's used by body builders and others pre workout to improve endurance. Well it just so happens that one of our members was taking it before exercising and accidentally discovered that it stops her itch! Many of us have had success with it since. Of course, talk to your doctor before trying anything. And a heads-up - Beta Alanine can cause your skin to tingle (ironic, I know). You should start with a very small amount (like a pinch) or you may end up as itchy as you would from an Aquagenic Pruritis attack, but for a shorter time. Then you work your way up to an effective dose without too much tingle.
