Hi bingen
I think if you're really using alcohol to sleep there are better and more effective ways to get sleep help - see your doctor for example.
A bottle of wine a night would be doing you some level of harm- alcohol is alcohol - it makes no difference if it's wine beer or whisky.

CDC - Frequently Asked Questions - Alcohol
Is beer or wine safer to drink than liquor?
No. One 12-ounce beer has about the same amount of alcohol as one 5-ounce glass of wine, or 1.5-ounce shot of liquor. It is the amount of alcohol consumed that affects a person most, not the type of alcoholic drink.
If you want support to quit altogether, you've come to the right place
