I did get really sick, I had a heart attack and was lucky to survive apparently. Of course, I got told I must give up smoking.......You could get really sick. Seriously, Heaven forbid, but that's the only way I could quit. The addict gene runs rampant on both DH & my sides of the family. My poor kids are doomed if they ever start anything addictive. At least now we know & we talk to them about the very real reality of such things.
