Not at all. Or maybe for you, but blanket statements like this are seldom true for everyone. After 30 years of smoking cigarettes I quit cold turkey, no problem. Couple years later decided I had given up something I enjoyed against my will and started again with the promise, which I've kept, that I will never smoke a cigarette out of habit. Only when it will be truly appreciated. Some days I don't smoke at all, some days I do, but I enjoy every single one (which I make myself).
