To save time (yours, I'm sure you're getting tired) I will say only that I did nothing to change my habits for the next 3 years. Then I did something different.
I had moved out of home and after finding a place with a friend decided I was better off on my own.
I moved into a house by myself and came at some point to the realisation that I could lose weight.
Someone had told me about a great drug you could get to help you lose weight FAST and you could eat whatever you wanted.
It worked - for a while - and I spent a great summer feeling the best I had about myself since 1992.
