This is almost like food poisoning but not. It started at 2:00 am last night. Woke up with the most incredible gas pains starting at my diaphragm and radiating into my back. Finally forced myself to vomit hoping that would make things better. Absolutely no improvement except now I can't keep anything down -- not even soft boiled eggs. I think the cause was a very rich chocolate cake. It was so rich no one could finish one piece but I'm the only one who got sick from it, which would figure since I do have a very sensitive stomach. So, what OTC medications are good for gas like this? There's no acid, just really miserable gas. I think if I could get the gas under control, the vomiting would stop. HELP!!!!!!!!!!!!!!
