From the age of 12 to the age of 40, I was a hardcore Mt. Dew addict. No kidding, no exaggeration, I put away several 20-oz bottles a day of the stuff. in 2009 I decided to quit cold turkey, picked a date, and did it. I am now 43 and have had maybe two indulgences of Mt. Dew since then. Some say it's all about willpower, I say it's all about being ready to make the change. Either you are or you aren't. If you are, then quitting is fairly easy. Good luck, if I did it then I know you can do it too. Commit and follow through.
