Hello to All!
The partial dose of the Soma helped me enough to be able to eventually do a little more searching here (once spasms settled).
I did find the Magnesiaum Thread on the Vitamin/Supplement Forum and was able to gain a great deal of helpful information from this! I am grateful to all of the thread contributors! I expect to be able to "get through" tonight with the spasms (they have quieted some) and will eventually have restored enough magnesium to be in a better place with muscle spasms!
I hope everyone has a peaceful, pain-free night of high quality sleep!
