Tried Charlie vodka (alcohol in general) for the first time

So I jus turned 18 today and decided to drink and bought 180ml of Charlie vodka I poured a few ml of vodka added sprite had it about 10 hrs ago and another time 2.5 hours ago but the rest I’m having it now so almost half or more than half the bottle. Is it bad? I drank it in like half an hour btw I don’t feel shit I just drank.Last I ate was 4.5 hrs ago Idk I’m new to this so help would be appreciated
