There have a short half life, which means that half is out of your system 3-4 1/2 hrs after taking
them, and gone from your system anywhere from 6-9 hours after taking
them. The wd's usually begin with watery eyes, and yawning at first, then progress rapidly from there. All of a sudden you need to run to the bathroom, then the sweats, chills and hot flashes and restlessness.
What they are now is probably as bad as they are going to be for you.
