I totally agree. If I waste an entire day messing around on the Internet, I go to bed with my mind frazzled. It's like guzzling a load of "empty calories" and feeling no benefit from them.

I've done the no-internet thing before for several months and while it wasn't a magic cure-all, I'd like to do it again. One downside is a certain feeling of lonliness when you're used to being able to swoop in and out of interesting discussions at any time of the day or night.
