Never tried alcohol. Am i gonna go all messy and talk unpredictable stuffs?

I’m 21. Tried weed a few times. In the weed experiences, i could control myself pretty well. But I never tried alcohol. Now, we some friends are thinking about trying it. Some have tried and some haven’t. And among this circle there are also my crush (I’ve been thinking about her for weeks and also kinda sad cause she might be dating someone else). So, is there any chance that while drunk, I am gonna say any unwanted stuffs to that girl (things i definitely don’t want)?
