Can I make a suggestion that might sound a bit odd? Instead of cutting down, for the first week you try to change your habits, begin by adding healthy stuff not taking away excess. With a mindset like yours, (mine's the same) if you start by cutting down, your body will think you are depriving it and rebel.
So, instead, start by adding 8 large glasses of water a day for a week. You can drink as much wine as you want that week, but you must also drink 3 litres of water. if by 8pm you've only had 1 glass, you'd better start knocking them back. If you hate water, add a splash of cordial to it.
The second week, keep up the water and you can eat whatever crap you want but you also must eat 8 full sized fruit and veg portions (a few lettuce leaves as garnish isn't a portion. Half a tomato isn't. Two entire little gems is. Half a pot of cherry tomatoes is.
Third week, add exercise, even if it's just a walk around the block each evening, or a 5 minute set of stretches before bed.
Keep a journal of what you're doing. Each week, develop it a bit. So by 4th week, you could be trying out an 8 min HIIT youtube video each night. Bit by bit you'll send your body the message that you are giving it things that take care of it, and then when you ease off the bad stuff, it won't feel like deprivation, as you have already replaced them with good stuff.
It works for me.
