I was having restless leg symptoms that was annoying me at night. But, I'm anemic so I just decided to take Slow FE Iron..and I don't have the jumpy leg feeling at night. I also take Baclofen for spasms right before bed..10mg. My left side is numb and I guess any tingling or numbness with that I just live with.. by the time I go to bed.. I am out cold.
