Quite the experience. Geesh! I am a chronic insomniac, usually miss at least one or two nights every week. Sometimes more but usually by day 3 or 4 I am able to sleep again. If it gets to 4 nights in a row I am a mess emotionally. Push it to a week and my heart feels like it is going to give out for all the skipping, I am usually shaking all over, the rapid mood swings turn me into a monster and my memory of the time is mostly foggy. I am amazed they do these kinds of studies actually. Seems to me it could be dangerous for some people.
