I was physically/mentally addicted to Coke. I don't think the physical caffiene addiction was that strong, but the mental part was. Both stress and boredom would have me reaching for a Coke.

When I began my diet, the best thing I did was to buy a good water bottle (Rubbermaid).

It's going to sound strange or funny, but I think I got used to bringing a Coke bottle up to my lips and drinking. Now, however, stress or boredom will bring that water bottle up to my lips to drink. Big difference in diet, yet the reflex or habit is the same.

So, what is it you are reaching for and why are you reaching? If you can't change the reason you are reaching, at least change what is available to be reached.
