Pain in my stomach, vomit taste when i burp, not constant, wakes me up, tums (calcium carbonate) don't help, gallbladder recently removed, i drink lots of water, ideas?

Reflux/Ulcer: Sounds like acid in your stomach is entering up into your esophagus. Ibuprofen can cause ulcers which may cause the symptoms you are having. I may try a medication like prilosec or zantac (ranitidine). If you have any difficulty swallowing, weight loss, blood in stool, or dark tarry stools tell your doctor as this is a sign of gastrointestinal bleeding.
