I used to drink DIET COKE all the time (years ago!), however now I only have it with a meal that may be hard to choke down (ahem....plain ass tuna, plain ass chicken breasts, etc).
<--------As ya can probally gather ... NOT a chef!!!
Anyhow, now when I have a can of diet coke with a meal, I never completely finish the whole can anymore. Which is...badass (since trying to veer more & more off it).
