I have recently been bitten and got the disease and completed the first mission, but I do not want it. How do I get rid of it. I can see any where to do this.
Go to the main city called Riften in the Rift Area. Enter the Mages guild building, go up the stairs and find an npc called Prelate Sabinus. Talk to him and he will remove your vampirism for a price. I think it's 200-300 gold
