Most people would think that's pretty normal and nothing worth mentioning but these people may not know my habits

Nah, I know a good chunk of people who don't drink nearly enough water. I also have family members who literally drink nothing but Pepsi, I've stayed with them for a week and watched, seriously, nothing except Pepsi 24/7. Shit made me wonder if they were all actually just the alien cockroach from Men in Black. Also, carbonated water that's flavored is goated though and you should give that a go over normal tap water, I'm just saying.

Also, as someone who dropped 228 pounds so far. You're definitely going to have mistakes as you go and it takes a little while to get into gear and stay there. Something that helped me a lot through the weight loss was fasting. I used to do 20 hour fasts everyday, now I'm just chilling at 18. I'd recommend you give it a go and see if it helps you. Start with a 14 hour fast and see how that works for you, if it's good/easy then go up to 16-18 hours over the following weeks and see how you do. An added benefit for me is my gut health feels way better fasting than when I didn't fast. Used to feel nauseous and acidic all the time, and that's went away now while I fast.
