Dose - First time taking valium (Diazepam)???

[Doomsday]

well a little background info first.
im a heavy pot smoker who used to live in ireland. my brother has been growing his own weed for the last 5 years for personal use so i always had a good supply.

but now i've moved to a country in south-east asia where it's hard as hell to get your hands on any sort of weed and when you can it's normally tiny amounts and you have to go through so much trouble to get it.

while i was hanging out with some of my cousins friends we smoked a few joints which was nice but they told me how hard it was to get weed here. so everybody just takes meth or valium with beer.

ok i've had no experience with any drugs apart from marijuana and cocaine (which i only did a few times) and it's pretty easy to get valium here.

my question is how much should i take for my first dosage??

i've heard that it makes you feel sleepy and relaxes your muscles and increases your appreciation for music.

im just looking for feedback here.

thanks.
