I too, took phentermine, still have like a full bottle someplace in the house, I hid it and now I can't find it anywhere. and like you, I took it to wake up and something to sleep at night, then felt kind of dopy all morning, its a viscous cycle. anyhow, I started having heart palpations, and an abnormal t wave and that scared the **** out of me, so I stopped it, no w/d, but stay away if possiable because it does raise your blood pressure and heart problems occure sometimes.
