Great plans.
I've never had alcohol, so can't really speak of how hard it may be to give up, but can say that the social pressures and enjoyment of being "in a crowd" are definitely the worst aspects of not drinking. People always view you with suspicion as if you're doing something against them, judging them in some way, rather than just doing something for yourself for your own reasons. Luckily, it's become much more common not to drink, so over the years it has definitely got less confrontational. I can't tell you how many new "friends" I've made over the years who were going to be the first to make me have a drink with them.
