Following day was fine. Half life of about 6 hours means it's gone pretty quickly. I'm pretty sure I felt mostly normal by 8 hours after I dosed.
Seems about as soluble as diazepam in ethanol. I used a solution of 2.5mg/mL, but I'm pretty sure it be more concentrated. I only want about .5mg-.75mg doses, so I didn't want it more concentrated than that. I'm not a heroic benzo dose guy, I am extremely skinny. My normal alprazolam dose for relaxation is about .5mg-1mg. Can't compare to phenazepam, because I gave that one a pass based on reports, halflife, and its chemical structure.
