I was on them for almost a year but they made me so lethargic that i decided to come off them. Having read somewhere that patients shouldn't just stop taking them, i began to take them once every two days for a couple of weeks, then once every 3, for another couple of weeks, until my supply ran out. I did not renew my prescription. Nowadays i am less lethargic and strive to steer clear of situations which cause anxiety.
