Makes me shake, sweat at night in bed, hot then cold, makes me very anxious have been having panic attacks. Tight in the chest and when I try to breath deep I have trouble. In fact it is making me dry heave and unable to breath deeply. It makes me want to vomit if I try and work out. I work out too hard I can't catch my breath. I feel like there is a lump in my throat and I want to vomit, sometimes I end up vomiting. I also have had what seems to be acid reflux. I burp a lot, and it is like air gets trapped when I try to breath deeply. Thanks.
