Acid reflux meds contribute to osteoporosis. I find I have to taper off them. You can stop Prilosec (omeprazole) and use Pepcid or Zantac to taper off meds. After a few days, take half, then a quarter, a few days each.

The thing is, when you take an acid reducer, your body says "I need to make more acid" so when you stop, your acid reflux tends to be worse. You have to slowly get your body back to making it normally.

I never eat after 5. I use Pepcid occasionally, and Tums. Tums has the added benefit of calcium even though not citrate.

For what it's worth, I tossed out all tummy acid drugs and relied on my grandmother's old cure after first learning about the PPI osteoporosis risk.

When I have an upset stomach of any kind, I drank 6-8 oz. of water with 1/4 tspn of baking soda. And it works for me 100% of the time. I don't have high blood pressure so the sodium from the baking soda isn't a problem.

My gastroenterologist said a lot of his patients have done the same thing successfully. It might be worth a try.
