I sometimes have trouble with the 1,000 words, too. If I have homework or something to do I usually cut it down a bit. It's more of a guideline thing for me rather than a rule. Exercise for me is usually taking a thirty-minute walk to the other side of campus and back, haven't really done the gym thing, haha.
And yeah, lab preparation can be annoying. I'm thankful that the prelab work for physics this quarter is actually a print-out deal where you write out the calculations and responses. In chemistry last year it was all done online, and it graded you as you entered in your work. It was picky, too. Often you'd enter in something like "1.56 mol" for an answer and the program would come back with "WRONG. 1.567 mol," and you'd want to punch the computer. But I digress. Like you said, you just have to do it bit by bit.
And I mainly write fan fiction. I used to read a little, but I haven't had much time lately. I would say txteclipse's "Eon Chronicles" is one of my favorites. He stumbled upon OL and we realized our fics had a lot in common plot and character-wise. Oh, and I don't have msn.
I also saw your PM. I had to do a double-take when I saw the title page of my fanfiction sitting on your Kindle. I think I had a reader who printed out OL and read it while waiting in the car for his kid after school, but to see the actual thing on a Kindle...that made my day.
And I read the comments. Looking back, I see I did have a habit of ending most chapters with someone sleeping. I don't know if that was a good thing; I imagine it made a lot of readers sleepy. I've made more of an effort now to end many (but not all) chapters with a cliffhanger. I think the most riveting books I've read end the majority of their chapters with cliffhangers (I'm thinking of Suzanne Collin's "The Hunger Games" right now).
The chapter length is crazy, too. I think the first chapter was a little over a page. But like you said, they got longer as time went on. I think for me now, a chapter is around 3,000-7,000 words.
