Funny you mention sleep. That's the first thing I lost once I came back! I'd go to bed early and wake up early. Now I'm doing the two sleeps a day thing. Short spurts with sudden wakes. A lot more chatter inside the mind as well; harder to focus. I won't say it's a disaster. Both versions of life are worth living, sometimes.

"Act now." "Do not delay." People feeling like they'll miss out. Winners/losers. Competition. The cheerleading/fans. I can see why it's all so hard for some folks to walk away from. Everything one has now feels like nothing when compared to the next big thing. All sense of accomplishment in the past is diminished. Once one starts chasing that feeling again, it does become that perfect pill. It does not get you high, it gets you hooked. Life is like that in general, as well.
