When you mention in your post "In terms of socializing ...........", after speaking of neutralizing the allergy effects of alcohol, do you mean this as socializing in addition to drinking or
not drinking alcoholic beverages. Because there was one occasion on my Camino when socializing and my inability to tolerate / reluctance to try alcohol caused me some discomfort.
It was on the outskirts of Sarria and my companions and I were checked into a private family run albergue. It was a lovely place, the hospitalero was very welcoming and all the pilgrim guests were invited to share the communal dinner. The usual wine was being drunk by many, and we were all having a good time trying to communicate with each other - there was no common tongue among us - and using a lot of sign language. Towards the end of the meal the hospitalero, I guess in an effort to be inclusive and to promote camaraderie, began pouring individual shot glasses of his home-brew liqueur, and placing a glass in front of each of us. When he came to put a glass in front of me, I demurred, but he placed it there anyway. As each pilgrim downed his shot of this, quite obviously, most vile-tasting concoction, the faces each person made caused great hilarity.
While this was going on I was trying to decide what, come my turn, was I going to do? Taking a swig of that stuff raised the great possibility that I would end up with a headache, my having to take my migraine meds, and being laid up in bed until at least mid-afternoon the next day - difficult to do in an albergue when they kick you out first thing in the morning. Not only that, I was walking with two cousins I had barely laid eyes on in forty years - in fact our Camino together was a sort of family reunion - and they had limited days to get to Santiago in order to make their return flights, and I did not want to separate from them. I could
not risk losing a day by drinking that liqueur. Aside from that, the last thing I wanted on my Camino was a migraine headache. When it was my turn to down the shot I declined, but it pained me to do so.
I still worry that I put the hospitalero in an awkward position and / or if I broke some sacred rule about accepting hospitality. But I really feel I had no choice. I wonder what others, in my position, would have done.
And those who feel inclined, can make fun of this too! I can handle it.
