LOL!!!! I totally stopped taking my Seroquel a little over a week ago and I'm STILL itching like crazy!!!!! Not non-stop, though!!!! The itching comes and goes. But when it's there, oh, man!!!! Is it there!!!!
I'm afraid I can't help you with why this is happening or what horrible damage we might be doing to ourselves, though.
The only reason you're getting this answer at all is because I Googled 'Seroquel' and 'cold turkey'!!!! LOLOL!!!!! I WONDERED if that's what's causing the itch!!!!!
Wonder when it will go away, too!!!! Good luck!! To both of us!!!
