I see my T twice a week - Monday and Thursday - which is perfectly spaced for me as I never have to go more than four days between appointments. If I had to pick only one day, I'd say Monday would be best for me, as I usually struggle more on the weekend when I'm less busy.

I prefer later appointments, too. Not too late, but dinner-time seems to work well - I'm alert enough for my appointment and it isn't too late when I get home so that I have time to decompress and journal before winding the evening down.
