I have been to a few AMPs over the years. I always do my homework and set reasonable expectations for myself before going into the particular AMP. Once inside, I do everything possible to make the provider feel comfortable with me from the outset including some sweet talk. And I always take the TS if they have one, even if I just showered before arriving, because it is the single best source of setting the mood in the room. I rarely have a mediocre session, let alone a bad one.
