'Tricks' used to pass time in general work pretty well for me. I try to do something that involves using my hands (or, you know, just not sitting in front of the computer/tv). Embroidery is my new favorite; gardening has worked pretty well; making myself get up and go for a walk; that sort of thing.

Really, any sort of hobby-like thing that reminds me to actually live my life instead of living my life between sessions.

If I'm insecure about time between sessions specifically because I want to see my T. I might give myself permission to look at my appointment card for x amount of time or write a letter to my T. for x amount of time before moving on to something else.

Hope that helps.

Take care.
