Welcome to PC.

Although this is my third post response about Seroquel in a row, your post caught my eye, because I feel I am dependent on Seroquel for sleep. Although I need it for other things too (Bipolar maintenance). I was on high dose Seroquel for a period of time and my body got so used to it. Eventually, I was hating some of the side effects and requested to come down to a lower dose than 800. Even 600 mg was giving me tremors, etc. I felt some withdrawal symptoms (insomnia) as I came down, but my body did eventually adjust to being on 400 mg and even 300 mg when I am "at my best." It is not fun to come down from being on a higher dose, but I felt so free once I adjusted. However, I am still completely dependent and cannot be off of it. Then again, I never tried to come off completely. All I know is if I don't have it, I am not getting any sleep that night.

Sorry, I didn't mean this to be discouraging! Basically just sharing that I can relate, and I was at least successful in tapering down with time, patience, and some discomfort, but you can manage. I think the idea above sounds like a good possibility: adding something as you cut down, if possible. I am on clonazepam, which only helps mildly, but it's better than nothing. I would imagine if I tried to get off Seroquel, it would help me to use clonazepam in the meantime.
