I generally go chain smoke about half a pack in 2 hours (until I can see straight & lock shit down enough to be mobile but not reactive // aka I'm not at risk for breaking my hand by beating the hell out of blameless walls, vending machines, people ), then get on the train (and ride until I can think straight, like where my actual destination is / change trains, head home), then face plant for the next week or so.
I occasionally vary this routine by heading to bar/restaurant instead, knocking back a beer or some bourbon, ordering takeaway, & eating in the loo or on the roof. This is a slightly more effective technique, I'm usually pissed the f*ck off & edgy for about a week, but that's more useful than flat out. I just don't usually have the money.
What I would LIKE to do is go swimming/sparring, full body exercise of some kind, to burn off all this shit... Instead of trying to lock it down. Both are even more expensive than beer & a sandwich, though. So, for now, it is what it is.
