Temperature Charting...Ugh!

I'm having a hard time charting my tempurature every morning. I sleep weird, usually I wake halfway up and even though I'm not completely awake I'm sort of aware I'm tossing and turning, pretty much off and on like that all night. At some point I finally wake up all the way, but I feel like taking my temperature is going to be useless from all that commotion.
What can I do? I really need to get accurate readings because all of my ovulation tests are always negative.
