Well, an antibiotic will destroy the good bacteria in your gut even more. Most likely it's the antacid that is causing trouble. Please seriously consider a pill form of acidophilus, since you don't have the added sugar from that which also wreaks havoc in the gut. You can get one that doesn't need refrigerating, which are just as good as the ones that do (look at the bottle description).

It also might be that you have food sensitivities or allergies you aren't aware of, that could be causing a "leaky gut." Have you ever seen an allergist?

Have you ever wrote your symptoms in a journal? When they happen, how soon after eating (and the foods), etc.

This is a little off your topic, Lisa, but it might help you, too.
