I am trying to get off of Seroquel XR 350 mg. Been taking it for about 2 years for anxiety and surgery related PTSD. The side effects are unacceptable...weight, sugar, cholesterol and liver enzymes are off the charts. Have tried to cut to 300mg ( with docs approval) but had nausea, vomiting, shakes, anxiety thru the roof. I went back up. I called Astrazeneca for their weening protocol and was told they have none!! Any ideas? I take no other medications.
