has recommended it. It is supposed to help with fatigue and sleep problems. I've been taking it for a couple weeks. Dr. Oz said to start 3 x a day for 3 weeks and then go down to 2 x a day. I'm not so sure if it is working or not because I've really been feeling lousy--still. It doesn't do much for the pain, however. I'm eating between 9 - 12 ibuprofen tabs per day.
