I'm doing it for the last time. I went cold turkey seven days ago and can't use any of the quit smoking "aids" because all of them give me nightmares. The first three days were easy. Day four contained about four hours of absolute misery and so did yesterday. Anyone been through this? How long do the really bad "jitters and I hate everyone" spells last? As in, mine last about four hours, but for how many weeks or months will I be getting them?
