upcoming vacation

I’ve made a lot of progress with noticing my thoughts around the moments I choose to over eat and eat off protocol. I’ve made the connection on how the old reoccurring thoughts create the reoccurring behaviors that have led me to the weight I am-and the hamster wheel of self-sabotage. I have a vacation coming up with a group of family friends which usually involves a good amount of drinking, and having a vacation mindset around food of “oh, who cares”.

Can you offer advice how to prepare my mind for this trip to show up for myself/my future self ? And once I am there and out of my daily routine, how to continue focusing on myself and my goals and not go back to the comfort of my past self?
