Yea weed knocks me out and I go to sleep. I get very drowsy and I can't do shit or wanna do shit. I get the giggles and some euphoria but still, I don't wanna knock out because I have some shit to get done.
With alcohol, I can drink for 8+ hours while gaming, listening to loud music and occasionally jacking off. It enhances all of that actually (while numbing the pain of sober existence obviously). By the 8th to 11th hour of drinking, thats when i get really drunk and drowsy. Then I will go into the deepest parts of the net for some reason and research into meta aspects of a lot of subjects. They call alcohol the truth serum but not for the reason you might think (blabbering outloud your dark secrets). When you get really drunk, you start to see and perceive the way the world really is (at this point, you realize that societal norms and your abiding by it, inhibits you from truth and happiness , and of course true happiness is knowing).
Even if for those moments, when I am super drunk and physically impaired. I swear I start researching into the very frontier of every subject, sociology, anthropology, physics, psychology, mathematics, philosophy of mind etc... Then I start to see the truth and everything for what it is. Then I knock out and wake up the next day with a massive hangover. But I was satisfied knowing that I delved into some deep shit the previous night.
