Just took 1.5 mgs Xanax as I walked out the the door at my probation officers office. Chased them with a big energy drink to stay awake. I prefer xanax to valium, mostly because they are cheaper. .5 mgs xanax costs $1 US, and is about equal to 10 mgs valium ($2). Temezepam I haven’t tried, but many of the benzos snobs on bluelight say it is the best of the three. But the one I’m looking forward to trying is etizolam, not controlled in the US (no idea UK). $200 US for a gram pure powder, or a tenth the price of zanax. Very similar in potency and duration.
