Sippy cup problems!

My three year old boy thinks he needs a sippy cup all the time, everyday all day! I feel like he is to old for it and I have had him drinking out of a regular cup during the day and allowing the cup at night but he throws a fit when I don't give him a sippy cup when he ask and I don't want him having it at night anymore either. It has become a huge fight! Does anyone have any tips or suggestions on how to get him off the sippy cup?

Just get rid of all the sippy cups. He cant use one if you dont have any at all.

That would be my suggestion. Yep, it'll be ugly for a bit. But I can't see it lasting more than three days.
