I have been taking Seroquel for three years- now the buzzing in my ears is almost continuous- I have methodically eliminated all thing that could cause this including magnesium. I tried weaning down to get off the Seroquel but that didn't seem to eliminate the buzzing, plus you dont sleep well- I have tried to get onto Z-Quil or Relaxium but they all contain magnesium and that makes the buzzing worse. Strong alcohol also causes the buzzing- so I switched to small glass of white wine and quit that before 6pm- not willing to give up alcohol as my thing is live music. If I had know about the side effects of Seroquel I wouldn't have taken it. Do not know how to get off this drug.
