I have been under a lot of stress lately, but 2wks ago i started having stomach problems. everything i eat comes back up within 15 to 30min. I feel this burning sensation in my stomach from the middle of ribcage to the top of my navel. It makes me feel weak, dizzy, I get a harble taste in my mouth, it feels like i have to vomit. this last for a few hours, then goes away.i have not been eating much but the pain still occurs.
