Omeprazole and good god

I've been taking Omeprazole for the last 4-5 days for the "possible treatment of H. Pylori" while we are waiting on a nuclear gallbladder test. After I started taking this I noticed my stomach going into cramps. Just like when you have a tummy bug and you get spasms or knots in your tummy. Very uncool, painful, and the only thing that seems to make it stop is eating and making my tummy full. (At least 90% of the discomfort and pain leaves when I do that) so I have been off of it for a little over 24 hours, and this morning I woke with some tummy cramps again. I'm thinking it may take a couple of days for everything to return to normal. I'm not going to take it anymore. (drugs - geesh - if you hear a commercial say it treats arthritis but may cause lymphoma - good god, why do that? Sorry I just think it's horrible about some drugs not that I have arthritis but I'd rather take a pain pill for it than turn around and get cancer)
