I have had a severe case of restless leg syndrome for the past 5-6 years. During a 12-week study at an area sleep clinic, my legs moved approx. 490 times per/hour. Although I have tried several medications, all made me tired during my waking hours and were not very effective. Since using your vibrating device, I find that I am sleeping more soundly and have discontinued taking my script for Provigil (a medication for shift workers and airline pilots) which helped me to focus and remain alert during the day. Thank-you for introducing this new technology to Cynthia and me.
