I think you get the idea. Therapy is mainly by being caressed and fondled, so it would be wise to pick a beautiful nurse. The good thing is that you can always say again and again: "Could you do that again" - and she will do just that - it's the treatment! And you can offer the treatment in return too, if you point out how repetitive she's been acting the last hour
Edit: Early symptoms are that you start humming "I got You Babe" by Sonny & Cher...
