I take bentyl, am newly diagnoised, and I was wondering what if you forget to take it 1/2 hour before your meal? Can you take it 20 minutes before you meal? How important is the 30 minutes? Dr. said I should quit taking it and see how I feel. I did and I got a bad stomach ache so that was enough to prove it does work. But how important is it to take it 30 mins. before you eat? Thanks.
