I have to say for me this is an unimportant question at the moment, the only way to test the theory is by practical experiment.
Weighing up the pros and cons its not an acceptable risk right now and I can't see a time when it will be.
Also the pleasure i would get from a couple of drinks every now and then is not comparable to the results should things go wrong.
Maybe when I have been sober a long, long time I will look at this again, but alcohol is not necessary for a happy life (or at least I bloody well hope it isn't) so I doubt it.
I think if I tried the old moderate drinking it would be self delusion.
I hope you think long and hard about trying anything like this vivid, although as you state its a long way in your future Im not worried for you yet. lol
