At six months if someone tells me they feel great all the time i get a bit worried.
I'm no Dr, but I would be reluctant to call that PAWS. After the drugs go and we come out of the fog we start to realize that life without drugs is life. Mood swings and all. Not only that, but we have a lot of regrets and uncertainty about where to go next, so to speak.
The steps and contact with other recovering addicts who had a lot more experience than me helped me through that, and still does when I get in a funk or hit a wall.
