Congratulations!
My tips for you and anyone else starting out OP is to count all points "no matter what." There is no going on or going off program.
Accountability is key. If you know what you are eating, you know where you stand, and your weigh-in will not be a surprise.
Also, pay attention to your non-scale victories. Passing-up foods that you cannot afford for better choices, working out when you don't want to, addressing issues rather than stuffing them with food, are all NSV. A bunch of NSV's will get you through the rough spots.
And, practice makes permanent. It takes time for your behavior to become a habit, so don't be too hard on yourself for hiccups.
My best to you!
