I found I was MUCH more sensitive to advertising prior to quitting, around the time I was noticing my drinking wasn't like 'normal' people any more. I'd have a rum and coke in my hand, see an advert (or people in a tv show or movie) happily people enjoying cocktails and I'd feel upset that I could only drink normally like that on some occasions, but on other occasions I didn't drink like a normal person.
I'm just short of 90 days sober now and the ads and people drinking on tv don't impact me like they did when I was worried about my drinking.
