Hey Courtney!
I often have problems staying on track with my healthy eating and here are a few things that I find helpful... I hope you don't mind the unsolicited tips...
- To kick the soda habit. I mix sparkling water and pure fruit juice. I get the bubbles I love and more natural sugars. I'm actually rethinking the sparkling water after an accidental experiment that I once did.... I was picking the stones out of the beans that I was getting ready to soak and a few fell into my sparkling water. About 10 minutes later when I finished my drink, the skins of the beans were so shriveled I was able to tear them right off. However, even after 24 hours of soaking in regular water and an hour of cooking, the skins didn't want to budge. Can you imagine what the carbonation is doing to our insides? EEEK
- I know planning and preparing ahead of time, involves time and energy you might not have but I find that if I prepare my breakfast and lunch the night before, I'll be sure to get healthy food in me and won't have to make last minute choices.
- I bring a cooler to team meetings/retreats at work, road trips, any time I travel or plan to be away from home. I take my cooler to work on a daily basis. If I have the food I'm going to eat for the day on-hand, I don't have to worry about leaving my desk to eat if I'm busy. I don't have to skip meals and I eat whatever it is that I've included in my program. I think you did this when you were traveling for work, I've found it helpful to do it all the time.
- Flexibility is important. Allow yourself the occasional treat as part of your program. I used to judge myself and feel bad when I would treat myself, I'd call it falling off the wagon and then feel bad and guilty for doing so. These days, if I've accounted for the treat in the whole of my program, then it's just part of my program. This works as long as the other healthy food that's supposed to be in my program gets in there too.

I think it's amazing that you're posting your journey on here and are sharing your process with us! Paying attention to what works and what doesn't is half the battle. Journaling is also the most helpful thing I've ever done when trying to lose weight.
Good luck and take care!!
