Hey Michelle. Im 16 weeks post l4/l5 fusion. Had the horrible leg cramps myself and mostly when sleeping.
I was told by an alchemist (stumbled on to this guy by calling some pharmacies to see what people had over the counter to help, I was hurting so bad). He told me that after enduring what we have for so long,meds, pain, surgery.. it depletes the body of important calcium in the body.
He told me that while I am waiting to call the doctor, if I did anything.. go get a good calcium/magnesium supplement. I did that day and that night.. I slept so much better! I have had only a few cramps since then. and before... it was constant.
I am not into the vitamin scene, but I have had great success with it to date.
You truly will start feeling better and better. It just takes time. Take care. Tammy
