Stomach pain, gas, and bloating are probably my worst symptoms when I am anxious. It is almost crippling to the point where I want to curl up and die. I have tried everything from Zantac to SSRI's etc. I finally found a combo that works pretty well. I take Xanax and Prilosec OTC. The prilosec gets rid of the stomach acid and the Xanax reduces the anxiety and the stomach cramping. There are still times though when I will eat something bad or get into the salsa a little too heavy and pay for it, but that is natural. I used to battle every morning with severe stomach pains.
