My doctor just put me on 15 mg. of Mobic per day to see if it's going to help my knees before doing anything else, had a knee replacement in one and the other is showing severe arthritis etc., I was curious as to the best time of the day to take it, I've been taking it at bedtime ... thoughts ... also, it doesn't seem to be doing much, how long does it take until it works, if it's going to?
