Drug info - First Time MDMA Questions

[its_a_mysteree]

ok, so swim is going to reading festival in a couple of weeks, swim and a friend of swim would both like to try mdma, (pure mdma theyve been recomended)
firstly, how much for the weekend (thurs-mon) is enough between them? (swim has been told a gram, should do it, [not using every night though])

secondly, assuming swim will take mdma on two alternate nights, is it safe for swim to consume alcohol on the other nights?
Also swim has heard that taking speed alongside mdma is best (and swim has taken speed before), any advice?

lastly, swim is confused as to whether mdma comes in crystal or powder form? if in crystals, then bombing it would be an appropriate method of taking it?

Also advice on easing the comedown would be good.
Thanks people!

(btw swim has never taken ecstasy, is it too risky for swim to try mdma, without having any tolerence at all?)
