I had my annual poke and prod yesterday and talked to my doctor about quitting. She gave me a prescription for Chantix and told me about the side effects. I tore it up when I left the office. Sleep is the only issue I have. I can exercise around the other stuff. Sleep tends to be the "great multiplier." Don't sleep, complete prick, kids are around, etc., etc. Melatonin, huh? Is it like Benadryl?
