Has anyone or does anyone have a indigestion problem with protein drinks? Everytime I take em I get a real bad cramp in my stomach, like I got a bunch of air trapped and cant burp an it gets to the point my mouth starts to water and I start throwin up. Anyone else had this problem? Its a pian in tha ass. I need protein it just makes me sick. I might have to stick to plain eggs and chicken and fish all day...
