Yes.
I labeled him an alcoholic in my 1992 book, Vessels of Rage, published in the UK (Element Books) as The Secret History of Alcoholism.
The most significant sign of alcoholism and the most difficult to hide is ... high tolerance. As I note in my book Alexander would challenge followers to drinking contests which he always won.
Add to that his impulsive behavior when drinking and his regret over it’s consequences, he’d have a hard time escaping the alkie Dx from a modern shrink. All Macedonians drank wine... often not mixed with water like the Greeks, it was how the alcohol effected him that was problematic.
