(1) Old English phoulcat (foul cat). Originally a reference to the fitch, the wild ancestor of the domesticated ferret, because of their ability to emit a foul smelling spray when frightened. (2) Later, used in North America as a reference to the skunk. Both are actually not cats, but members of the weasel family, Mustelidae.
The symptoms of withdrawal can last for a few days up to a few weeks. It really is dependent on each person and their personal addiction. The most common withdrawal times usually last somewhere between a week and 14 days.
Honestly, there will be 2-4 days of acute withdrawal. 2 nd and 3 rd days are the worst after the last drink but this differs in every person. The detox is not that long. For most people, it will take as little as a week.
