I know how difficult it is to give up a habit as I'm a smoker as opposed to a drinker----of which I don't touch drink.
You have to start by reducing your intake, which can be done rather than stopping altogether.
Both habits have proven to have direct links to cancer in some way although we also know that cancer occurs in those who don't drink or smoke but when you do it exacerbates those areas within your body that are " beds " for cancer growths.
Start by buying your two bottles of wine and eke them out to last you for the week----you can do this by having one glass after your meals and perhaps another glass further into the evening and if you stick to this you'll only need your two bottles a week-------just make sure it's the average wine glass and not a tumbler ! Drink a glass or two of water in between.
Over a long time of " rationing " myself, I can manage my habit, although I was never what you call a heavy smoker, I can make 20 last me 3 and even 4 days. I'd never buy in bulk/carton. If I run out I can do without them.
You're not old so now is the best time to begin some sort of regime before you reach your 70's if you want to remain fit in old age when you could find yourself falling due to balance not being the same, mixed with alcohol plus other ills when you replace food for alcohol which is a slippery slope in old age.
I understand that this is a choice with each individual adult but if you want to carry on remaining reasonably fit, then begin by asking yourself why you do it, do you need as much as you're having and finally, do you WANT to reduce.
It's not something you can stop overnight and nobody expects this to happen, least of all your body ! A day at a time and some deep thoughts about your future health.
I wish you luck on whatever you decide as it's only yourself who can do something about it.
