I've been taking Mobic for about 1 year now. I can't tell that it is really helping my fibromyalgia left from Lyme disease. Some days, I can hardly move. I have noticed that I bleed much more easily. Little nicks actally drip blood now. I'm going to quit taking it just to see if that is part of the problem. Every time the doctor's office draws blood, the tech seems concerned and asks me if I am taking a blood thinner.
