I get pretty decent results from using it, but if it bothers you, try Prevacid
. You can also try to take something like Maalox or Mylanta, or even Pepto
-Bismol, although that will turn your stools black.
The stomach pain is, obviously, not good. It could be gas that is trapped and you can't get it out. But since this is going on so long, I'm not sure.
I know you said you don't have insurance, but a visit to a clinic might be worth it just to get some idea from a doctor if this is serious.
