I feel sick when I don't drink too... and drinking would make it worse for an hour or so, then "cure" it right up. So I do think it's normal. It will pass. If it gets bad, talk to your doctor. I've been gagging on and off this afternoon, and all I've drank today is ice water, even at the restaurant. I struggled a bit to finish my favorite meal, too. When I drink, I eat like a pig. Can't wait to see the pounds start falling off now.
