So sorry, Snoods.

My spasms are always worse at night too, but, unlike you, I find that a few stretches do help me a little. But they can keep you awake and uncomfortable you a long time..
When I took that spill, recently, my spasms got much worse...ouch!...especially at night. I take a couple of asprins, if the spasms are bad at night and I find that helps to get me to sleep, faster.
I have read that Magneseum supplements are good for spasms. I don't take them but maybe I should. Some people swear by it.
Anyway, wanted to let you know, you're not alone and I hope you find relief soon..
