I think spacing it out is better than two nights in a row if possible. I go on Mondays and Thursdays, and that works well for me, as it still gives me time to process in between sessions. When I used to see ex-T and my former marriage counselor, I often saw them on consecutive days (ex-MC Monday and ex-T Tuesday) and realized that was too much to process in too little time and switched to usually having ex-T Wednesday instead, which helped a bit.

That being said, I have seen current T two days in a row before for an extra session, either if he and I had a major conflict or, in one case, when there was something major going on in my life and I needed more support. Those were helpful. But I wouldn't want it every week.
