my blood tests showed that in the weeks running up to the tests I'd drunk more than the "recommended" amount, I felt that it was a ridiculous decision to treat me as a full blown alcoholic.
I see two massive red flags here.
One is the excessive drinking up to the tests ( which you knew about ) and the subsequent denial of a problem.
From your previous posts you have three strikes already.
Vision issues, history of depression and alcohol abuse.
No matter what the rules allow most professional pilots are not daily drinkers.
There is just too much at stake.
Hence the decision by the CAA.
