I like the way reddit handles this. I know there's a lot of reddit refugees on here anyway but just so we're on the same page: r/gaming for memes, r/games and r/truegaming for discussion.
Assuming you mean cutting soda out entirely and not just diet soda, I just want to reassure you that it does get easier. I've gone from drinking a can or 2 at lunch/dinner to only drinking like a handful of times a year (only at parties/events for social purposes). In my experience after the 6 month mark, soda straight up tastes bad and at that point it's smooth sailing. Your teeth and wallet will thank you.
I am but a simple creature. I get some kind of primal satisfaction from going to the gym and lifting heavy things so that I can lift even heavier things in the future.
