[criddell]

I spent years reading a little in bed before falling asleep and I wish I had never started doing that. I've conditioned myself that reading leads to sleep and now it's very difficult for me to read for long because a few pages in I start to feel sleepy.

Same, but I don't think it's the conditioning itself, it's just being comfortable. I can't watch/listen to a video of a presentation either and struggle sitting in at presentations.
