2M2B carbamate has been/is being sold by the gram from a company that usually deals with bulk (1 tonne cubes) chemicals. Just the GABA part was JUST like alcohol but without 'the dark corners'. I cannot see someone taking it and turning into a complete twat.
I thought that random carbamates can potentially be quite dangerous / toxic? ...
GHB / GBL were most of the time very warm for me, cozy and gregarious. But especially at lower doses effect on GHB receptors can give that effect, quite stimulating in a way.. it is only at high / full doses that the GABAergic action starts to dominate.
And yes, 2M2B smelled like mentholic campherous terpenes. Pure well-made GHB is mostly tasteless (not particularly disgusting as unreacted GBL can be), but still salty cause of the sodium and vaguely ychtious.
No I won't say 2M2B is particularly bad, I liked the lack of hangover, but it is also very easy to get wrecked (black hole!) cause of the potency - it can be like drinking half a bottle of vodka in one go - pretty dicey. Especially tricky for people who are careless or reckless.
I've been dependent on GHB but fortunately I never upped the dose compensating for tolerance.. so I could just stop and have a bad day or aid with something like gabapentin - and on one january 1st I just left it behind me without much thought. Strange, but glad I did not really go deep into the addiction upping the dose. Still, all that sodium!
Personally, since messing with GABAergics too much (benzos etc) and getting chronic withdrawal syndrome from that - anxiety insomnia the whole shebang... I am more careful and apprehensive about it - I never take superhigh doses of any such thing, and make sure to leave enough off days or weeks so that actual dependence doesn't return. It's worse than opioids to get addicted to IMO and I recommend huge caution with them.
