Good luck with getting off weed. I think you'll find after any possible PAWS (I don't care what anyone else says, there's definitely some depression/irritability that happened when I stopped smoking weed and I think they were related) goes away you'll be a lot more stable.

I'm still in my first few months of quitting weed (and opiates) but I've been able to stop taking Seroquel except the occasional PRN dose (usually for sleep). I'm doing a trial without prazosin and with a smaller dose of cogentin too and so far so good. My risperdal and propranolol stayed the same, but I'm hoping to come off the propranolol at some point this year.

It really is a "we'll see what happens over the next year and adjust meds as necessary" situation.
