I have a sensitive stomach, along with food intolerances, and so there are things to try, with diet (avoid processed foods, sugar, dairy, whole wheat and night shades). Otherwise, there are good practices on webmd that can also make a difference. I am on Pantoprozole, but I also take an acid reducer at bedtime. I drink hot tea (chamomile) before bed as well. For sleep, I ended up with a sleep study and also cognitive behavior training (!!) and that really helped. No sleeping pills, but I do 5mg of 1:1 marijuana.
