Last night after eating, I fell asleep in my chair, and when I woke up and started moving around, I noticed gradual onset of stomach discomfort. It stated again this morning after I ate, and then this evening. I was okay sitting at my desk all day. I have noticed over the past 4 months or so, I get the heaves and throw up sometimes after eating. I do drink one or two alcoholic beverages daily, I m a diabetic on Metformin, Valsartin, Zocor, low does aspirin daily, and a daily multivitamin. Is this just gas or more serious. Normal BMs.
