Is it possibly Aciphex? Are you allowing enough time after you eat and before you go to bed for your food to digest? I never allow less than 3 hours, and sometimes it's 4-5. A friend at work is eating her main meal of the day at breakfast (a casserole or some other dinner fare) , then a medium lunch and only oatmeal at night. She is just trying to lose weight, but I think it would work well for GERD sufferers as well.
