thanks for your help Ann, I've actually taken ALA before and it made me very sick so I'm steering clear of it. I must say since I started taking the supplement with zinc and molybdenum in it yesterday I feel great! most symptoms have been dulled significantly! Mayb copper is more of my problem.. O and i used to be sensitive to alcohol too, now I can handle it quite well, except beer that increases my symptoms about 10 fold the day after I have it.
