Aha! You aren't even on an antacid. You need to ask your doc about starting one. (Bariatric patients all need to be on antacids for several months postop). Since your doc's office is likely closed today, you could try asking your pharmacist if an antacid would be ok. Pepcid complete (over the counter) is what I take, but I have no way of knowing if it might be a bad idea in YOUR case. You are the best! I will call my surgeon tomorrow and see if he can prescribe an antacid. Greatly apréciate your support.
