I mentioned somewhere else in the thread, but I'm exercising a fair amount already, and in my case the traditional reward for a solid workout is a vape session so while I do intend to keep it up I'm sort of maxed out in terms of using it to compensate. Regarding sleep – in my commuter days the insomnia would wreck me but my schedule is a lot more flexible now so I think I'm going to try to ride it out with just some melatonin. Re caffeine – somewhat maxed out there too, I drink about a pint of high-grade Colombian iced coffee a day which is at this point a well-established personal upper threshold for well-being.
Thank you
