Is It Normal to Become a Crying Mess After Vodka?

So tomorrow is my last board exam and my friend and I are planning to drink vodka after it ends. I’ve only tried vodka once before. The first time, it felt great in the beginning, I was singing with friends and everything felt light and fun. But after some time, I suddenly got emotional about a friend who had been ignoring me. I ended up calling him and crying a lot on the phone. It was honestly embarrassing afterwards. Now I’m a bit scared that the same thing might happen again. Is it normal for alcohol to make you emotional like that? Does it depend on mindset before drinking? I don’t want to ruin the vibe or do something I’ll regret again. Would appreciate some honest advice.
