My doctor put me on omeprazole, and he said to take it on an empty stomach an hour before eating. Obviously, this means not to eat less than an hour after taking it, but do I actually have to eat something once an hour has passed? My schedule is such that I occasionally have to skip a meal; if I know that's going to happen, could I just take the pill around the scheduled time and forget about the food? If not, does it have to be an actual meal, or can I make do with a snack bar or something?
