In the last 2 months my DR. reduced my aderall from 60mg to 40 mg and alprazolam from 2 mg to 1 mg last month I started a paxil taper to 0. So now I'm at 0 and I know it's got a short half life but I have been taking it so long 15 yrs I wonder how long it will take to be out of my system I always feel this is the hardest part at 0.
