I had to cancel most of my plans in early sobriety. I had to protect it as the precious gift it really is. I'm at around 10+ months and I still prefer not to be around drinkers or drinking situations.. as I'm a non-drinker.
I also had to change up who I thought were my friends.. but it took me a while to weed out who was and who wasn't. For the friends that stuck around (because they were unphased by doing non-drinking things with me), they know how important my sobriety is. My drinking buddies.. eh, I don't care. I do have to say, when I first quit drinking and I had the ridiculous idea to still go hang out at my local bar, once I said I quit drinking.. none of them offered me a drink or asked me to. That's just completely disrespectful and insensitive. Maybe your friends don't know that this is a LIFE change.. and critical to your well being. I would question any friend that encouraged you to drink at all.. they might be struggling with the spotlight on their own issues then.
I have to look out for me and my sobriety, no one else will!
