Ross & anewbody2013 - I have a suggestion. It helped me a lot. Plan, plan plan your meals. I know I'm kinda crazy and can plan for the whole week, but try planning
for just the weekend. Doesn't matter how you do it - before I started doing my own meal prep, I had gotten some Healthy Choice breakfasts, lunches and dinners solely for my weekends. Once I got used to having 3 pre-portioned meals and 2-3 snacks, I was able to move on and portion out my meals for the weekend. You don't have to do it forever; it took me about a month or two to get used to appropriate portion sizes. And, if you do it during the week, you shouldn't feel yourself being very hungry on the weekend.
However, if it's the mindset of "It's my weekend, I'm not distracted by work, I can finally pig out" then, I would suggest some mental conditioning as well as some weekend meal prepping. As neurotic as I am, once I had the prepped meals in the fridge, I didn't want to deviate from them so my trips to the fridge would indicate that it's either time for an allotted meal or a prepped snack. In my mind, I saw this as "oh, cool, less work for me" when I went food hunting in the fridge. Again, it's the same amount of food you're getting during the week, and it's important that our mind listens to our stomach when it's telling us we're not hungry.
Good luck

You got this!
