Just drink booze instead. Drinking soda alone can't be fun. You'll just feel awful.
That won't do him any better. I'm underage so I don't drink, but there would be no difference. Alcohol is an addiction just like pop in this sole case. If possible, get addicted to some ice, cold water! It's healthy, keeps your body flowing with hydrogen and oxygen, and could taste good especially now that we're getting out of the cold and into spring and warmer months.
Trust me when I say this: There is a huge difference between an alcoholic addiction and a soda addiction. Also trust me when I say that it nearly impossible to be addicted to water, there are ingredients in soda that triggers someone to form an addiction, because our bodies are still in survival mode, we crave sugary things, and soda has a lot of them sugary things, and it was a good instinct to find and eat all the sugary things in pre-mass food production society, and it still is in many parts of the world. Water has very few of the sugary things, and it is tasteless, so there's nothing you can really be addicted to from it, so in short: Alcohol addiction and soda addiction are very different with many different consequences on both, the reason Dave is so addicted is because of sugar and evolutionary things, and it's hard to be addicted to water.
