Praying for sleep...

So the last two nights I have woken up in the middle of the night with excruciating pain.  Two nights ago in my belly every time I moved and last night in my back, constant and stabbing.  Third tri officially sucks.  Since I have to actually work tomorrow and see more people than just my husband (specifically about 100 12-13 year olds who are not nearly as understanding about mood swings and sleep deprivation), I am praying that I can actually sleep all night- in my bed- without horrific pain that wakes me up.  Wish me luck!!
