I have had very bad acid/GERD problems for years and anti-acids and drugs like omeprazole avoided the problems your fiance has. Recently, however, the drugs aren't helping and I even have to try and get to sleep through such pain. I have read that it could be a sign of a peptic ulcer so I'm off to the doctors next week and I guess, so should your fiance. Don't think they are anything to worry about these days with modern drug therapies.
Oh btw I can eat all I lke and not put on weight too
