I know just how you feel. I have been having stomach problems for almost 2 years. One day I woke up totally constipated and had to get what the doctor called the big guns to free up my system. Then I noticed I couldn't eat fruit or veggies anymore without having gas pains that made me go to the er thinking I was having a heart attack. After 3 or 4 visits like that they thought I must just be nuts and they put me on ativan for anxiety. I have been to a gastric doctor and had a colonoscopy that showed nothing, ekgs, cardiac stress tests, cat scans, ecocardiagrams and still nothing. Nothing but gas most days, constipation or loose stools and still chest pain. I gave up things like my allergy meds, switched nexium for prilosec otc, and have discovered a line of over the counter supplements from digestive advantage. I have been taking the one for lactose intolerance, the one for gas and the one for constipation. This week I actually don't feel as if I might die in the near future. Maybe you ought to try to weed out things you are ingesting for 3 or 4 days at a time and keep a diary of how you feel and what is going on with your system. Maybe you need to recolonize your digestive tract with good bacteria (check out digestive advantage) and see if it makes a difference. Good luck, remember you're not alone.
