People looking for a easy way out are not yet motivated to the point they will quit for good. Go into it with the attitude quitting will be tough. Very, very tough, but it only takes a few weeks to get over the hump.
And don’t try and quit anything else at the same time. Drink, eat - whatever. One thing at a time.
That’s what I try to tell my wife. She won’t stop smoking because she doesn’t want to gain weight.
