Oh, the wine, the wine
. Know exactly what you mean, there! Maybe try buying the small bottles so you have that thing that 'the bottle is now empty', where you have to make a decision to open a second? Or get 5.5% alcohol wine? Just suggestions, as I drink full fat wine, just trying to be wine-free 3 or so days a week, having just one 175ml glass on 2 or so evenings, and then maybe 'overdoing it' on the 7th! (I believe in 80/20 per week as in 80% observant, 20% blowing it! A bit!). But deal with one 'vice' at a time. Cutting down wine and food simultaneously would be too hard for me!
But as for the eating-Hmm. Is there someone you trust eating with you (ie will help you not use your weight or diet as a 'weapon' against you, however unwittingly)? Someone who can step in when you say 'I think I'm full now' who can quietly take your plate away- make that 'break' for you?
Maybe you should only serve yourself what you know is likely to 'satisfy' you, maybe on a smaller plate? Once served, if there's any left, box it up to freeze immediately before you eat your serving? So it's not just sitting there on the kitchen bench! Take it away from your eyeline.
Could you put small pictures or typed phrase as reminders of what your goals are on the fridge door, the biscuit tin? Even placed discretely beside your plate at mealtimes? They might just be enough to make you go 'Hang on'!
Remove temptation from the house at this early stage; no cakes, biscuits, chocolate. If it ain't there, you can't eat it!
I keep Ryvita handy for 'those moments' Whilst I'm not supposed to be 'calorie controlling' my diet, 42 cals for a rather nice cracker's OK by me!
I know what you mean about the 'full' feeling being disappointing. I was literally half way through a delicious roast at mum's the other day and was aware I was getting rather close to being full- but couldn't decide whether to eat the veg or chicken to get me there! I decided one more mouthful of each, then took my plate into the kitchen. I thought to myself 'A thin person would just stop at that, and as I want to be a thin person, I shall make myself do that til I am that thin person and the ability to walk away from 'enough' food, once satisfied, comes naturally'. Doesn't always work but I believe it does get easier with time and repetition.
It sounds very much like habit to me (tho I'm no expert) as you don't appear to be attaching any thought process to it (like 'oh, I may be hungry later, better eat up now'/ 'I must never leave any food on my plate'). Maybe you feel 'anger' at having to deprive yourself of something you love? That it 'isn't fair'? I recognise that in myself! But I try and replace that with the thought that I'm doing myself a favour, not putting in more fuel than I need.
I hasten I don't speak from any high-ground. I am quite 'new' to deciding to lose some weight, and have lost a mere half stone in 3 weeks. I am aiming for a 2 stone loss and am doing it via PMc, soem calorie 'awareness' and 3 x 30mins fast walking on an inclined treadmill!
