Pretty often I get this kind of a pressure over my chest, the feeling of needing to burp but stronger. Then I can go around for a hour or 2 and burp and then finaly I usualy can push out one big ass ****ing burp and the pressure leaves.

But its anoying as hell cause sometimes(but only happened once or twice) I burp so much that I feel like puking.

This also only seems to happen when I take ephedra. Why the hell do I get that?
