I am also tapering off of Seroquel I was on 200mg xr and 200mg at bedtime. I started tapering down the Seroquel at bedtime at 50 mg increments every two weeks. Then I started tapering the Seroquel xr at from 200mg to 150 mg every two months . I am now on 50 mg of Seroquel xr. I also take .5 mg of clonazepam twice a day. I have had some episodes of insomnia so I am now taking 3mg of melatonin at night to help me sleep. The problem is that there isn't a lower dosage after the 50mg of Seroquel xr. Which makes it difficult to taper without any negative side effects. ( for example rebound insomnia). So I guess we are both having the same problem.
