I feel your pain. I have problems with stomach acids also. Been ongoing for a while now.
I get nausea from any of the following; when my stomach is full, I don't feel full, just nauseous, laughing hard for more than about 10 secs, crying, and nervousness.
Now, I know it's common for those types of things to trigger nausea, but mine is not normal. It happens too easy.
My doctor recently put me on a 15 day sample of Nexium to try to correct the problem. It worked amazing during that time and I never felt better. My next visit I'll ask for a prescription for alot more than 15 days.
