The commercials and trailers and other promotional crap which seems to account for at least 30% of the programming are what drove me to get rid of my TV 10 years ago. I just cannot stand it for one second. The stupid put-on voices, the excruciating music, the assumption that we're all dumb, the same visuals and dialog over and over and over again...I have no idea how anyone can sit through that without feeling stabby.
Beepster, I too suffer from insomnia but they could never get any of those drugs into me. I tried sleeping pills years ago and I hated everything about them. Over the last couple of years I've gradually worked out what causes it and have been able to alleviate it to a large extent. I'm convinced that one of the main reasons was staying up late in front of a bright screen in a brightly lit room. This messes with sleep patterns so much. So what I did was install fl.ux on my computer, and that warms and darkens my computer screen as it gets later. At night it's a mellow orangey glow and it really helps wind me down. I also removed any "full spectrum" lightbulbs from my apartment and replaced them with the bog standard yellow kind (although pretty soon we won't be able to buy these - thanks politicians!). On nights when I feel like I'm not going to be able to sleep, I also take 3mg or so of melatonin which works wonders for me and is totally natural. If I don't have any melatonin I'll eat a large bunch of bananas and that seems to do the same thing.
