Omg had my second experience puking up stomach acid or bile in the back of my throat while I slept!! that's such a horrible experience. and I even took a tums before I laid down :( I don't have anything else I can prop my self up higher with in bed, and if I did I think it would just be uncomfortable sleeping, and I really don't want to go buy the expensive prilosec otc for the Last few weeks.
