Boy, does that sound familiar. My cardiologist gave me a prescription which I faithfully followed and felt absolutely NO desire to quit by the time it was finished. This was early October, 2008. I knew smoking was bad and I'd like to quit. Problem was I didn't WANT to quit & there's a big difference. I smoked my last ciggie on Dec.8, 2008 and underwent quadruple bypass surgery on Dec.9, (Yay Trillium!). I had refilled the Champix perscription in November and deliberately timed it to finish while I was recovering from the surgery. It worked perfectly! My wife doesn't smoke & would never buy me a pack and I knew my 'enforced' abstinence would preclude wandering about the nearby shops in search of nicotine. I couldn't drive (or even walk) to the variety store once I got home (winter in Canada) but I didn't WANT to! The craving had completely disappeared! I still 'hang around' smokers but stand upwind as the smoke just stinks. I have what I would call an 'addictive' personality whether it be coffee, booze, smokes, aspirin, etc. I stopped drinking in 1984 and it was easier than kicking smoking! As for side-effects, the weirdest thing for me was dreaming of kids I went to public school with (c. 1959-60), names I thought I'd forgotten. I almost wish I'd had scary dreams, I'd write 'em down & get them published. Poor old Stevie King needs some competition these days. The bottom line: I thank Pfizer and my cardiologist for Champix, smoke-free for almost two years and NO cravings. Cheers, Dave
