Whoa Debra!!! Whoo hoo, what a way to celebrate the 4th of July! Awesome job. Did you jump around and do a little victory dance after the weigh in? I certainly did, but I bet your's was prettier.
Maintaining isn't for the faint of heart, I can tell you that! #1 Tip: Do not stop logging your food. #2 (And I am sure you know this) Treats, are still treats even though you are no longer officially dieting. So sure, have a little cake during a celebration, but don't make a habit of it.
One mistake I often make is reverting to old habits of eating lots of carbs - not necessarily unhealthy ones, but definitely more breads than I really need to. I don't have much of a sweet tooth - salty/crunchy things are my weakness. So I have stay pretty disciplined to avoid over doing the chips and crackers.
Have a great 4th, it certainly started off on the right foot.
