I have not smoked for three weeks now(with the help of chantix). The craving is not there at all but I hate it. I feel like I've lost my will to live, my best buddy, my everything. I have terrible gas, constipation,weight gain and really don't even feel like getting out of bed in the morning as that was the first thing I did,sit outside and have a couple of smokes and coffee.So far the only reward is the money. I feel like an outcast with the horrible gas I've developed I don't want to go ANYWHERE. At work almost everyone smokes,this doesn't help much. Simply... I hate everything about not smoking, but I still want to stick to it. Has anyone else felt so horrible about doing something that's so good?
