Professor Geoff Greif is quoted in a melmagazine.com story that looks into this topic. "It’s pretty easy to tell when you’re done with most medical treatments: You either finish the prescribed medication, or whatever it was that was oozing/bleeding/itching/flaking stops what it was doing and you forget to take the remaining doses. Either way, it’s pretty cut-and-dry.Therapy, on the other hand, seems different — more open-ended, with less tangible goals. So after you’ve been going for a while and you feel like you’ve achieved some level of personal growth, how do you know when you’re good to go (or rather, not go anymore)?"
