How do you feel when you start getting tipsy?

I barely drink, like once every 3 months and it’s only ever one glass, for a while now I’ve been wanting to get tipsy but I’ve been hesitant because of my fear of throwing up, Ive never been tipsy so I have no idea how it feels or what signs that I’m getting tipsy and was wondering if anyone could tell me what it feels like when they are so I can have somewhat an idea as to how I’m supposed to feel

Another question is what is a sign I should stop drinking? And if I end up somehow doing too much is it possible to reverse my chances of throwing up by drinking more water and eating more food?
