"This was the 1st night in months I actually slept 8-9 hours. Took this little pill at midnight. Actually, woke up at 5 am due to pain in left knee area due to previous medial/lateral meniscus tear. Had arthroscopic surgery approximately 2 months ago but still painful especially at night. Doctor claims pain is due to arthritis so I sleep with a moist heating pad wrapped around the knee to ease the pain. After waking at approx 5 am, re-wrapped the heating pad around knee and fell back to sleep within minutes. I&#039;ve never been able to return to sleep in the past. I used to walk the floors after sleeping 3-4 hrs. Slept until 9:30 this morning."
