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.

There are other products on the market and available at your grocery stores. You can google and compare SW to other electrolyte products. If you are known to have electrolyte balancing problems being followed by a medical provider check with them first, if you haven’t already done so.
