It's insanely potent and builds tolerance rapidly, with major withdrawals compared to others. One of the most euphoric in my opinion, but requires considerable caution. the difference between 0.5 mg and 1.0 mg could be the difference between a good nights sleep and jail time.
Probably mg for mg the most potent benzo regularly available these days (strong hypnotic effects, with a xanax like disinhibition punch (it felt almost like xanax and ambien combined to me at first).
Careful redosing if you take it again, and PLEASE try not to drink too much on it, or it could end bad...
