I've tried everything, and the only things that make any noticeable difference in my experience:
Modafinil, Racetams, Noopept, Phenibut
Noopept seems to be curiously missing from this list?

Very fun substance also nasty as fuck and undoubtably bad for your brain. (I got weird neurological "withdrawal" symptoms after like 3 days of taking it)
Spent 8 continuous hours vomiting with the worst nausea I've ever felt in my life.
Lesson hard learned. I've been using Phenibut for nearly 10 years, I only take it on the weekends.
I quite enjoy high doses, feels much better than drinking without negative physical side effects. I don't drink alcohol in general, to be honest.
