For the past week I have had this feeling of being sick, I don't feel ill and my stomach doesn't hurt at all. It's just when I move around I feel like sick is coming up my throat, then I just burp. It's really annoying since I actually feel like in going to puke. It's mainly bad at night, specially when I get in bed, when I drink water it goes away for about 60 seconds, then it comes back! I don't live the most healthy life style, I don't eat regular dinners and I don't get much sleep, I just snack! Oh and recently my throat has started to feel a lot tighter, what could it be?
