I too was put on hyocyamine for two years. I was told to take two caplets three times a day, and I did this for two years! now that i've researched it I realized that it was probably stupid to take them all the time. However, I was 17 at the time and figured doctor knows best. I finally stopped taking them altogether, because they became a huge hassle and barely worked. I think I might try to peppermint caps. I hardly ever get indigestion or heartburn, so hopefully they won't have a negative effect in that arena.
