Wombat wouldnt recomend more then 30mg, on the other hand, as an experienced benzo user and licenced medical doctor, as well as working for a large pharmacutical company as the director of benzodiazepine research and production, I WOULD! .. in fact, I would recomend at LEAST 60mg before you even consider embarking on a journey .. the thing is, they don't "get you high" as much as they make you tired and put you to sleep..
*NOTE - I am not a doctor nor do I work for a pharmacutical company, I am a junky that likes to abuse his medications, benzos are among said medications, and Restoril is among the crappy suck benzos that I actually have a bottle of but don't take as it takes several hundred mg's for me to catch a buzz...
