I am a regular smoker, about a pack a day. This morning around 11AM, I smoked a cig and right afterwards I broke out in a sudden pouring sweat, almost passed out and threw up 3 times. I thought maybe it was because I had a slight hangover from last night. So I didn t smoke another cig until just a few mins ago (6:45PM), same thing. Pouring sweat, almost hit the floor and puked my guts out. I definitely don t want another cig, but what is wrong?........
