I would assume that's what Rokko does when he's stressed out.
Rokko, please understand that I'm not trying to give you a lecture here (I still smoke and used to drink 2 pots of coffee a day)...but Goddamn, man, tell me you're not doing that kind of thing on a regular. If you can quit that kind of shit now, you'll be so much better off in the long run. It's so much easier to do when you're younger, IMO.
I started smoking and drinking coffee at 19 (I'm 28 now). I kicked caffeine a year ago, but the smoking is still an issue.
