I have tried it. It is very much like alcohol. It depends on the dose. There is some euphoria by way of stress relief.
I must warn you that it is highly dangerous if you take excessive amounts. I once took 600mg on a really bad day and I was pretty much unable to function at all because I was so intoxicated. I later slept for 13 hours. Next day I felt even worse.
The only thing Nembutal is used for these days is suicide, so that needs to be considered if anyone near you knows what you have. Keep it locked away.
Frankly with the way the world is headed I really wish I still had some. But I abused the shit out of it and ultimately ran out and then turned to alcohol (went through 2 litres of cream sherry every 2 or 3 days). I suffered a trauma in May last year and that is what started it. Initially I got the Nembutal for suicide but basically used it to obliterate all of my mental anguish instead.
It is dangerous stuff. The withdrawals can be fatal as well. I had nasty electric shock sensations when I stopped it along with totally crippling anxiety and distress. Absolute hell. Then I did something just as stupid and turned to booze. Trust me abusing CNS depressants isn't worth it. Your life could be ruined just like mine was. And guess what? My road to hell started with one flimsy little 50mg dose. That is all, just 50mg got me hooked because I was trying to suppress very difficult emotions. It fucked up my life, to be perfectly honest. Abusing Nembutal is a VERY bad idea.
Make sure you respect this white powder. Don't use it all the time and don't get hooked on it or like me you will be so very sorry!
