Short T1/2: This medication has a very short half life which means quick on and quick off. If using to help with anxiety before bed, typically take within 10-15 minutes of planned bed. It will most likely be out of your system between 2-4 hours depending how long you have been using and your metabolism.

Xanax (alprazolam): It is anxiety medication, not sleep medicine. Unless otherwise directed by your doctor, the last daily dose is usually prescribed 1/2-1 hour before bed.
