It doesn't exist but I'm sure I'm not the first/only person to think about it.
I want to go to the drugstore tonight, buy loads of sleeping pills. I'm on vacs right now so I can afford to sleep for a whole week. During that week I'm going to hibernate and feed on extra lean food...say...nuts...just a lil bit.
And I'll sleep the whole time, just to erase the first few kilos. Who has tried this before?
