I really want to stop taking this drug , I've been taking it now for about 7 years and I've had enough . My highest dose I've ever taken was 1500mg in a one day crazy I know , at the moment I am having very bad effects from using it daily , blurred vision, headache, confusion, horrible taste in my mouth, I literally want to sleep all the day , I can't continue like this, it is disturbing my whole life , how do I taper off , I've tried before and went back to taking it after a few days , I need help please.
