I know you are heavily addicted to soda like me....I have to drink one a day to stay awake though.

Have you ever heard of a Sodastream? Its carbonated water then you mix syrup being sparkling water syrup or soda. it cuts down on price of each thingy like each syrup thingy makes 9L of soda and costs roughly like $6 syrup bottle. The 60L Carbonator comes with the sodastream and so does a 1L bottle some units you can pay extra and get syrup as well. I own one myself. ITs an option, if you can put the money out to the machine.
