I had sessions first thing in the morning. When I was in a drinking relapse, I would get drunk after each session, right in the morning, and email the T. It wasn't specific to therapy though, I did that 2-3x a week during that time. That was pretty horrible. When I resolved the relapse, I would either go to work or work from home during the day, but still emailed the T most of the time post-session. I never did anything specific to calm down and the emailing wasn't really helpful, more another bad habit.
