2 * 125 = 250 ml, which is 1/3rd of a bottle.
Most wine is stronger than 8% ABV, and so the portion size should be smaller.
Note that France used to have high rates of alcohol related harm, but have managed to reduce those after a long public health campaign of raising prices and lowering drink drive limits.
OP is clearly drinking at levels that are harmful, even if OP isn't dependent. OP is drinking well over the recommended 14 units per week, and OP thinks it's causing harm.
It is a mistake to think that only dependent drinking is harmful.
Harm is caused even if the person isn't dependent on drinking.
We know it it's a problem because OP is asking for help.
It's unlikely OP is drinking 8% ABV wine.
3 bottles of 14% ABV would be 31 units a week - well over the recommended maximum.
And if he cut down to 17 I wouldn't be mentioning the recommended limits. I keep mentioning them because other people keep saying OP's not drinking that much. OP's drinking more than double the recommended limits but more importantly OP has noticed harm is being caused.
