restless legs syndrome
"Dismal results from other restless legs syndrome medicines, 500 mg Horizant has been a welcome relief. Especially the nausea that always accompanied the other medicines. Noticed relief the first day. While it hasn't completely eliminated the restless legs syndrome issue, I can easily say it has made an 80-90% improvement. Minimal side effects noted  slightly itchy skin and occasional watery eyes. PLUS I am  sleeping much better"
