I used to drink about six cans of Coke a day. Here's what I did:
1 Limited myself to one can, consumed right after riding to work. (none on weekends).
2 Started drinking lemon seltzer water as a replacement.
3 Began drinking fruit juices.
The can of Coke is the day's big treat. If I do something energetic (like ride 10 miles towing my kid in a trailer when it is really hot) I allow myself a second Coke.
The result was I began losing a pound a month sinch I started this two years ago. Also, I enjoy my morning drink, but no longer crave it.
