"i have had restless leg syndrome all my life. nighttime was awful, kicking my legs, rocking,and only fell asleep because i was exhausted. been taking 15mg nightly. wake up once and fall right back to sleep. never in my life have i been able to sleep like that. i am 65 years old, once in a while feel groggy. also helps with restless legs syndrome during day. feel more calm as well. my husband says i don&#039;t even move at night and no more black &amp; blue marks on my legs."
