Unfortunately for me, I haven't found that to be true. There have been times when I thought surely, eventually, my body would give out and I would sleep - but it never happened. I just go crazy loco and wind up strapped to a bed and injected with something to knock me out. Now I get in a horrible cycle where if I don't sleep for a couple of days, I worry that I will continue not sleeping and wind up in the nuthouse and that makes me not able to sleep. So, here I am, not sleeping and starting to wonder, taking warm baths, drinking hot tea, meditating, reading War and Peace and taking every sleeping pill or possibly slightly sedating pill I've got to ward that off. I think pharmaceutical companies should start testing their sleeping pills on me. I'd be the ultimate guinea pig. Send the sleepy vibes this way too please....
