Hi all thanks for the welcome , I should of been taking quetiapine the last few months as prescribed by doctor , but stupidly went against his advice because of work which involves driving . I was very drowzy so stopped taking them . Now i have had to quit job so am starting them again as the doctor prescribed . The packet doesn't say prolonged release so i am assuming they are immediate release . I am taking 50mg at night at the moment and i have been told to steadily increase up to 150mg .
