Stop in for a cup of coffee

Not that you were going to do anything anyway, lol... But from personal experience - just take it easy afterward. I went to work right after my first shot. Nothing strenuous, but changed a lot of lights that night plus a few other jobs. Started getting sore that evening and felt like I got punched the next day. Second round (which most people say is worse) I took off work and relaxed didn't hurt near as much.
