Sickeningly so.
Petronski, maybe you remember some of the late 90's rumors about Michael's scieno involvement, as you are well informed on the scieno's? I've heard rumors of his involvement before, and that Terri's injuries were indeed the result of dieting, only it was one of the scientology cleansing diets, used on/by her because she wanted to bail on Scientology and return to Catholicism and he didn't want her to. I don't think he's (openly?) a Scientologist now.
Sadly, I don't have that information. I do know that the Scieno cleansing routines are very dangerous to the heart (basically, dehydrating the body and throwing the electrolytes out of whack). Beyond that, I don't know.
