Thank you for those balanced replies - I was afraid I might trigger off the crusaders against booze!
I posted the question and phrased it as "too much" because I wished to acknowledge that guidelines have been set and my intake (35-50 units per week) exceeds them and is classed as "hazardous". That is a genuine figure - doesn't need to be "factored" - because this is an anonymous forum and I don't need to BS anybody.
However, my military flying was also hazardous, could easily have knocked years off my life, and was accepted because it was emormous fun.
The reason for asking was twofold. First, I am fed up with being told about the risk when I believe that I understand and accept it, just as I understood the deal with mil flying. Second, I want to hear all the arguments so that I can be sure I DO understand the score.
Although I am perhaps not best placed to judge my effect on those around me, I really do believe that there is no problem there.
