How do I tell my friends I'm sober without making it weird?

Telling friends you're sober can feel awkward, but it doesn't have to be. You can be direct and say something like 'I'm not drinking anymore for my health, but I still want to hang out.' You don't owe anyone a detailed explanation. Suggest activities that don't revolve around alcohol. True friends will respect your decision and be happy you're taking care of yourself. If some friends drift away, it might be because the friendship was based more on drinking than a genuine connection.
