Same problems with the cramps - other suggestions:
be sure to stay well hydrated (even in the middle of the night if the cramps strike), also OTC Hyland anti leg cramp meds and I take prescription muscle cramp relievers - omeprazole in my instance (PRN)

Lastly, I keep an electric massager plugged on my bed (~$30-40 at Walmart) to turn on and use if needed. I kind of push the vibrating ends into the painful muscles (usually calves or thighs), sometimes really almost gouging with the more pointed ends - there are choices. That gets to the spasms in the leg muscles which can get to feeling like stone.

I also stretch my calf muscle. I lean against my bed with my feet pressed against the floor , sometimes knead the calves with my own fingers.

Good luck to you all. I know how painful it can be.
