nah you don't have to say anything beforehand. I've been taking a break from alchol for years. I'll just invite the girl out for a drink and then just get something cheap and barley touch it.

Good on you for quittting alcohol, the thing is an actual toxin.As for the dates I would look for girls that prefer not to drink or not drink altogether but maybe that’s just me.I feel like that if you’re making the effort to stop drinking surrounding yourself in an environment where there’s a lot of alcohol and people getting wasted is probably not a good idea.
