I’ve tried using a computer as my DJ. The problem with that, though, is that I have to get completely out of bed, go over to my desk, wake up the computer from sleep mode, unlock the screensaver, possibly open a text-editing program if I didn’t remember to do it the night before, and finally start typing. That’s like a full minute of prep time. Plus the screen is really bright. >.>
I’ve also tried using a little tape recorder next to the bed, so that when I wake up I can just reach over, pick it up, and start recording with minimal movement. This would have been great, except that I found I couldn’t always understand myself when I played back my recording. Often I would be too mumbly to be audible, or I’d say things which probably made sense to my brain at 3 AM while half-asleep, but would make no sense later on.
So I’ve settled on a little black bound journal that I really like. I still have to get up and turn on the light, but it’s less movement than the computer, and I can keep the journal by my bed for easy access. I’ve found that I have decent handwriting even when I’m sleepy. (The light’s gotta be on, though. If it’s not, I’ll think I’m writing in a straight line, but then I’ll discover later on that I’ve written up and down the page haphazardly, sometimes writing over other lines. D: )
I’ve found that I can’t just write a list of keywords and go back to sleep, because the list may very well make no sense when I look at it again. On the other hand, if I try to write every little thing down, it can take a while (depending on how much I remember) and my hand gets tired. So I try for a happy medium.
