The first session I thought, oh, this is a piece of cake, but its the second one that will really put the whammy on you. A friend told me "Be sure you take some mints with you when you go into the room because you can taste medication." They do an IV drip, but it was so very potent. I remember I could smell it, I could taste it, and when I went to the bathroom I could smell it in my urine. It was just that strong.
