Yes, that was a really helpful shared experience, thank you!

Basically, it enforced my point of view to only try it out, if I really think it is neccecary.

I never done cocaine, but weed.

With the right time and settings it can help me get into a flow lasting for 10+ hours. But weed really does not help mid or long term, my productivity goes into steady decline after couple of days.

And coffeine I never liked, so I prefer the natural rhythm, with varying success.
