Has to be a can, never a bottle

I went to the dentist recently. I was told that they will not perform anything slightly complex on the NHS (although an NHS dentist) because they do not make enough money from it. Super.

I was also told that my diet coke habit is rotting away my tooth enamel and that I would have to give it up. I did as asked and promptly had withdrawl symptoms for several days afterwards.

Cannot give it up entirely though - currently enjoying an illicit can :-)
