Hi, I don't know how long you were told to take your medication for but its really important you finish it as that tends to be the common mistake- people usually start feeling better before finishing theirmedication and stop taking it. It is possible that you don't have mono anymore but not certain which is why they usually tell you to finish taking the medication. By not finishing it you are risking that the "weak bacteria/ virus" has been killed off but the "stronger ones" are still in your body. I would suggest you get it checked out again just to make sure it is gone.
