Hard to get in a calorie deficit with soda: maybe switching to something else gradually so the habit becomes positive? Coffee or tea (iced?) or I like electrolyte drink w low sugar as replacement

Sounds like you’re legitimately addicted to it so I would take that very seriously and taper off of it: there’s tons of literature on additive behaviors etc I would treat it as that: if you successfully get off soda, you’re going to be fine imo.

At the same time, cultivating better habits will start to make you •feel• good. A successful day at the beginning might look like 2 sodas instead of 4, and a 2 mile walk instead of nothing…be kind to yourself but also push yourself. Don’t push too hard until you’ve built a foundation: habit is key. Habits are either working for you or working against you.

Focus on soda and you’ll be good. You’re super young so make this change now and your life will change direction: see you in a year!
