Congrats to you for making smart, healthy changes! Lifestyle changes are difficult and it sounds like you're doing great
I've lost 125 lbs with about 30 more to go - when we went to WDW this year, these were my favorite tips:
I drank water like it was nobody's business. Water is your best friend. On an average day I get 80 oz - in Disney I bumped it up to 100 oz a day (94 degrees outside in the sun walking all day, yikes!).
I shared literally everything with my husband. Even if it was a snack, I'd take a few bites and he would have a few bites. Not only did that help with portion control, but it helped us be able to try lots of different things
I limited myself to one "treat" per day - be that an alcoholic drink or a sweet treat or pasta/bread. Otherwise I stuck to protein first (always. My cardinal rule, haha), veggies second, and starches last.
I lost weight on our trip, and didn't feel deprived of anything. Good luck!!!!
