I get this too, when I have a good session. I won't want to go straight home, I'll always want to go somewhere afterwards, even if that means to the grocery store. It's like I feel so free in the couple hours afterward, you know? With a bad session, it's the opposite. If I can feel the "high" coming, I'll always say to myself "enjoy it while it lasts, because you'll just end up back to normal in a couple hours".
