I have IBS, so too much caffiene or onion content in food gives cramps that can wake me and keep me up, as well as runs and if it's extremely bad, Montezuma's Revenge.

There comes a time when you indulge, knowing full well you've set yourself up for an attack, and what I've done is pre-emptively take the medicine (Loperamide HCL in my case) before bedtime.

Esophageal (sp) erosion is terrible and must be avoided, since my aunt has really bad Barrett's and it's caused her to eat extremely bland stuff - spaghetti (marinara) sauce is too spicy. Nexium is helping some in making her more tolerant of foods. I think Barrett's is also known as a Hyatal Hernia.
