Caffeine rarely. So, like today I'm drinking I've got a tea mix. This one is um I forget the brand. This has 15 milligrams of caffeine, but I don't drink caffeine on a regular basis. To me, it's an escalation when I start doing it. Uh, I just have to have more and it just soon I get addicted. So, only on occasions like today, this is really fun. It's Sunday morning. I'm hanging out with you guys. I'm having fun. And 15 grams of caffeine is just a nice little boost.
