I've called my T maybe 4 or 5 times within the past 6 months or so (didn't call her much the 3 years before that), when I've needed extra support because of something that just happened. I have her cell but have always just left a voice mail on her office phone (I've been told I could use the cell for emergencies or a last-minute appointment change). She's called back each of the times (usually same day) and talked to me for anywhere from 10 minutes to a half hour (most of her drive home). Also in that time period, I tend to send her 1 or 2 e-mails a week, often just processing something from our previous session, sharing how a session with our marriage counselor went, and/or mentioning things to talk about for next session. She only responds occasionally, and it's very brief, but she will mention the e-mails in session.

With MC, I've left him probably 6 or 7 voice mail messages on his office phone when I felt the want/need to talk to just him and/or was upset about something from the session (also over the past 6 months or so). He generally takes a day or two to call back, but a couple times, he talked to me for a half hour, another time about 15 minutes. I recently got his cell number, but am saving that for an emergency (confirmed it's OK to call in that case). I've sent him maybe a dozen e-mails if I was upset about something or just wanted to tell him something without having to discuss it in session (generally transference-related stuff). He'll respond if I specifically ask him to let me know he got it, but that can also take a day or two.

(I'm not counting calling for cancelling/scheduling appointments.)
