but not as a sweetener. I don't drink diet beverages, but I recently tried d,l phenylalanine which I found at Pro Health. I get a lot of supplements there, but something about the name bothered me. In any case, I tried it and felt it really helped my mood. Then I did some research and found out some scary stuff. Does anyone have info on where to find real facts about this stuff. please help!! Maria Sorry I have been away from the board again, but I had just had a terrible flair and then a death in th family, so it's been rough. Not to mention my computer was out of service for 3 weeks in there somewhere. You don't realize how much you rely on it till it's not there!!
