Sand Paper Lips??

can somone please help me out, I plan on making a dr appointment once my insurance kicks in from my new job. I noticed for about three-four months now that my lips have become sooo dry and flaky, if I lick my lips they feel like sand paper. I drink a ton of water the only other drink I have is coffee in the morning. I've never experienced my lips doing this so when it first started I went and bought chapstick, carmex, lip balms, lips masks and nothing seems to be working. sometimes they get so dry that it hurts to smile. not sure what's happening to them, came out of no where. also the weather isnt bad here. its spring weather right now.
