Good going! I would like to toss this out there- no amount of social expectation or peer pressure can override your need to be sober. No matter the culture, anyone who expressed dismay that you're not drinking and expects you to be drunk next time...WOW! Just...wow. That person needs to look in the mirror. That type of ignorance isn't going to help you at all. Instead of examining your reasons for quitting you should examine the company you keep. Maybe a lifestyle change is in order.
Rant mode off!
Congrats on the 90 days!
