When I had my penis replacement surgery I worried I wouldn't be able to remember to take my meds. Turns out, when I was late taking them one day, I had a sudden urge to have sex with Paris Hilton. Clearly my penis was rejecting me, and seeking a self-destructive path.
When this became apparant to me, I took the meds, and my craving for Paris Hilton was immediately replace by a desire for apple pie.
seriously this is all in good fun. If you're anticipating a new organ I certainly wish you the best. If it is a liver, see if you can keep your old one, and if it is actually good with fava beans and a nice chianti.
