The ceiling is blurry

I am the mother of the bride. My daughter is not one of those Bridezilla creatures. In fact, she's very organized, very calm. But still, at night, I find myself unable to sleep. It's not that I am worrying, but rather all kinds of details that need to be done the next day all bombard my mind tormenting it so I can't sleep. And with the wedding being held here, I have even more details to keep ironing out.
So finding myself wide away, staring at a blurry dark ceiling, I lay there, hours on end, each night.
Insomnia runs in my family, but it's hitting me hard. The stress of an upcoming wedding,things that need to be done in the course of a regular day, and me being of that time in my life, have all conspired to keep me awake at night.
And it doesn't help that my hubby is sleeping soundly next to me as though he hadn't a care in the world.
So I pray, I reorganize my upcoming day, I meditate, I do pretty much everything I can to coax sleep onto me.
That's why I am here, at 4-something typing this out, asking for help.
What do you mothers of the bride or groom insomniacs do to cope?
