I love water! However, I used to be a big diet pepsi drinker (about a 2 liter a day). I quit all artificial sweetners last year, because I read a book about the dangers that scared the living daylights out of me. I started drinking carbonated water to get the bubble feel. If you really like soda, you can try that for a while and see if it helps.
If you want to read the book it's "Sweet Deception" by Dr Mercola and Dr Pearsall http://products.mercola.com/sweet-deception/
