Yes, I've had a colonoscopy and they looked into my stomach too. No diagnosis except gastritis. But I've pampered my stomach for so long you'd think by now it would have healed but no. Do I get nausea, sometimes. Do I have pain, more than sometimes, weeks at a time. I get up each morning at about 4:00 to eat and have some tea and pills depending on how I feel. Then I go back to sleep for a few hours. I sleep A LOT. Too much I think. I'm sleeping my life away because of this THING. I can feel myself going downhill physically. Don't feel like doing anything.
