Chalmette -my MD has me taking it at bedtime - and if i literally take it and go to bed, i am asleep by the time the stomach ache hits.... if i wait, then i totally get it and the queasiness too.
For during the day, I am finding that if i eat really well (with no sugars) i have less stomachaches and queasiness then otherwise. Also, if I eat about 4 small meals a day, I do better.
Hope that helps =( Kiya
