Ugh, I have some of the same reactions.
With Facebook, when a person constantly posts photos of drinking (or their drink!) or makes positive comments about drinking, I think, "that is not a safe person, and I don't want to be around them." I think on FB you can choose to not see feeds from certain people.
A few years ago, when I smelled someone reeking of vodka, I had a physical reaction of nausea. Now, when around people drinking in a social situation, it's beginning to not bother me.
