My dad died in 1999 with people thinking the same after a triple bypass in the 80's. He quit for 3 years, started running marathons, did the whole 9 yards. I never believed a nicotine craving drove him back to it (actually, he blamed me, but in a tongue-in-cheek way, sorta like saying the dog farted...he did that alot, too). I didn't understand about the maoi thing, but I did understand the calming effects that are unique to cigarettes, and saw that as something he needed that didn't come from exercise or diet.
That's some story. I was fortunate I guess. My Dad was a smoker and an alcoholic. He died while driving a tractor drunk, 2 weeks after I got married. Years ago I was a social drinker but luckily it never went any further. I was able to say one day that I just didn't want to drink any more.
A2D: Try Discreet. There are very few choices for domestic snus. Many find Camel and Marlboro too sweet and/or not strong enough. Discreet is tasty and has 7.4mg of nicotine (just about perfect). Online outlets like getsnus.com have Discreet at very reasonable prices (six new packs arrived in my mail today; strawberry and peach). They are mini pouches, invisible in use.
Thanks TB that gives me some guidance. I looked at OTD's score card and was kind of lost sa to what to buy.
