How to ask doctor for a stronger medicine so I don't take so many others ?

Make an appointment with your doctor, and say "Hey, so I have 3 bulged disks and disk degenerative disease in 2 disks as well as torn ligaments an other stuff. I take a bunch of pain killers, but I get tired of taking so many pills. Could I get a stronger pain killer that I would only take once per day? Thank you!"
