sleep again

So the night I posted of my sleeping issues I slept the whole night! For a whole week I slept great. Until I mentioned to Pat how great it was to sleep at night, on Saturday. For the past 2 nights I have not slept at night. Saturday it felt like I drank diet coke all night and the caffeine was keeping me awake. Last night I fell asleep a little after 10 PM but woke up at 12 AM and couldn't fall back to sleep,sigh. I am so freaking tired today.
