Root Phone doesn't go to sleep CM7

[androidn00bie]

I'm using a rooted phone running on Cyanogenmod 7.1 for the Mytouch SLide, and I noticed that suddenly, my battery drained way too fast overnight. It loses like 40% just by sitting there for 7 hours. When I go to spare parts, it says the time spent without sleeping is about 12 hours. When i go to usage statisitics, the apps Funny Jokes, GO Launcher, Settings, and Dolphin Browser are what are up. Any solutions or ideas?
