21st Birthday Tips???? 🎉

Mi
Hey girls so I am turning 21 soon and have NEVER had a drink. Besides a sip here and there over the last year from my dad saying I won't like beer and me proving him wrong by trying it with him. I have my designated chaperone covered by my cousin, she's going to make sure I'm good all night and drive me home. I just moved and have no friends so girls night is out, so what do you guys recommend I do for my birthday?? What do I drink?? What tastes the least bad?? What can I do to AVOID a hangover, besides not drinking?? I live near the casinos in CT so think I might slip over there too, anyone have thoughts about them for drinking??
