Sometimes I get hungover and puke for 12 hours straight, other times I’m not hungover at all

Does anybody else get like this? I’ll drink the night before, and this last time I had only had 5 or 6 drinks throughout the night so it wasn’t crazy. And the next day, I will be throwing up from when I wake up around 8 or 9, until evening usually around 4-6 pm but last night and the time before that I got hungover it was until 10 pm. Other times I’ll go out and drink like either the same amount or more or less (what I’m trying to say here is that the amount of alcohol it is does not seem to dictate the hangover the next day). And then this is more the norm, I’ll be very slightly hungover and groggy, or not at all. So it’s either the absolute worse, or nothing at all. Something to note is that around two years ago there were a few times I had literally no more than 3 drinks the night before and puked for a bit the next day. It’s very confusing and annoying. I haven’t been able to find any answers about this and was trying to see if anybody else is like this.
