@Veets888 - I find that when it appears I have more mucus than normal I increase my water intake and that seems to clear it up.  I do not drink  coffee, tea and very rarely pop or similar products so that would not be a cause in my case.  I would discuss this with your doctor and see what he or she feels.  I do know that it is suggested that you drink 1 1/2 times your weigh in ounces of water each day.  My best to you.  Linda ( moderator, Bladdercancer.net team member)
