20 is a lot. I mean if you're taking it just to unwind seems like you could get by on as little as 5.
I have only used it for medicinal reasons-pre-dental (5-10mg), sleep aid when recovering for surgery (20-30mg).
I'm all for unwinding... just be careful as your body builds up a tolerance to them. If it's 20 now, you'll be at 30 and so on. I'd rather see a brother find a way to unwind that doesn't require increased dosages as time goes on... Now if 5mg would work forever....
Your body does become more tolorent to the drug.. I took 50mg last night.. All it did was smooth me over. Not really any effect at all. I'd stick with 10-20 mg and not let your body get to use to it.
