I too have noticed I've been spending less time with my old drinking buddies. I myself have been making less calls to some of those people but that's alright, it'll sort itself out. Your best friends will understand the importance of the commitment to health you've made and stick with you. Hell, a few of them might even surprise you and back you up.
30 Days is a major milestone with powerful momentum behind it. Newfound strength you can and will use to continue making good choices for yourself and your loved ones.
Anyway congratulations on making this goal 4Thorns, it gets a lot easier, then just an afterthought as time goes on. Your body and mind are no doubt starting to heal and you're likely feeling some of the positive effects. You can look forward to feeling even better and more confident with a great sense of freedom going forward.
Best,
