While the rest of the world would go on vacation if we were exhausted, Demi Moore has gone to rehab. You know, because the 12 step programs work really well for exhaustion. Besides, Demi just came back from a two week vacation. Apparently doing nothing all day can really tire you out. Of course if you are snorting something up your nose then even if you do not do anything, you are probably staying up for days on end. Demi could be exhausted from the will power needed to not get anything to eat. Do you wonder now if the young guy she was seeing was providing something to her? Maybe making a little trade? Not saying sex, but maybe just some pap photos? A little publicity can do a career some good. I don't think anyone has been shy about talking about Demi's substance issues ever since Ashton Kutcher cheated on her, so I don't know why there is all this hoo ha about exhaustion and improving her overall health.
