I also have that problem, though less now that my stress level has gone down considerably. Mine was a mix of lactose and gluten intolerance. While I can now have some of both, the best suggestions I have are:
1. Try probiotics with a bifidobacterium strain (lactobacillus is okay, but doesn't seem to work as well) every day, or even twice a day.
2. Try to lessen your intake of uncooked milk products as well as gluten (wheat, barley, rye, spelt).
While neither of these is likely to take 100% of the problem, neither will interfere with existing meds or health issues (though I am not a doctor yadayadayadda...). I hope it helps! I do notice that, though I do not have celiac disease (yay!) I still bloat up like a blimp every time I have too much gluten, and bread is a major weakness for me now that I can eat it without being totally miserable. Good luck! (If you do want more info on this feel free to PM me as I was completely gluten free for over 6 years)
