I bought homeopathic #8 magnesium pills at whole foods and it works wonders for leg cramps. I had a misdiagnosed (by foot doc) numb foot for five years. The foot doc said I had over exercised doing sciatica exercises and that it would take a long long time to heal. Now my GP thinks I have neuropathy and has me on 600 mg. of Gabapentin. It seems to be helping with my sleep and my foot.
