restless legs syndrome
"This has really helped me. I have had RLS all my life off and on.  The RLS is worse now,  I am 74yrs.  I have been on it almost a year. I believe I may be getting some side effects lately. I am so tired, and can't seem to think straight sometimes. I realize that could be from other things, but I am going to talk to my Doctor on next visit.
It is a God send if you haven't slept for nights."
