Channel surfing

I don't know if I should blame it on last week's cabin fever, or that I'm really tired of winter, but over the past few days I can't get any sort of grip on my ADD. I never considered it worth medicating, especially as I'd learned some methods to rein it in when needed. But over the weekend it was if I was playing a one-person game of raquetball inside my own head. I couldn't get to sleep last night as I couldn't turn off all the channels. And although I'm drowning in work, my lack of focus is not helping me. I don't know what to do.
