My opinion is that there could be such a thing. BUT I don't think it would be helpful to try to work out some rule about the "right" amount because this is so individual for each person. For example in the above posters, Wheeler went three times a week after hospitalisation, and that was what was needed, and great that it worked for you and helped, Wheeler. For me, if I went three times per week, at this point in my therapy, I think my case would be more like what Xynesthesia suggests, that I would be becoming obsessed with therapy to the detriment of other things in my life. That's because I'm not at a crisis stage and I'm slowly coming towards the end of therapy. So what I'm saying is that each of us just has to figure out where we are at and what our needs are, and whether therapy is helping more or hindering more at a particular point.
