Wow, im also going through heroin withdrawal. Decided to go cold turkey with the help of suboxones. I have been off my seroquil for about 5 days. My boyfriend got the idea I needed to google seroquil withdrawal. Im amazed of the symptoms im reading is what im going through. I have the shakes, shivering, cold sweats. Here im questioning why my detox from heroin is so bad. An it was my seroquil. I picked up my prescription a little bit ago and took my prescription. Im thankful for this sight and to everyone that has added information.
