Quetiapine stopped working at 50mg after about a week. My pdoc won't give me benzos and even though I don't feel manic he keeps saying it's underline maina that's causing the insomnia (I hope he's right). Today he said I need to start taking seroquel (generic version) at 150mg I recently was trying 100mg and it didn't work so I pray this finally gives me sleep. Also will the severe dry mouth side effect last forever?
