[24F] Is it normal to throw up everytime I drink?

I apologize for getting into detail about this but I need to know why I suddenly get sick everytime I drink alcohol, after years of being able to drink a copious amount of it. I get sick everytime I drink alcohol even if it’s just a little bit – I’ll have two drinks and puke. I’ll have one shot and puke. I try to eat before I drink but I end up puking it all up 20 mins later. I drink a lot (around three times a week lately, but I take months off periodically), and when I do drink I definitely drink more for what a 5’3” 130 lb female should drink lol. Tonight is christmas eve and I had four glasses of red wine, then i ate dinner and went outside for a cigarette, and brought my fifth glass out with me. I then puked outside halfway through my cigarette.

I have a feeling this happens because of my past alcohol abuse but I just need to know if there could be any other reason or if there is any way to mitigate this. I’m also confused because there are nights where I can drink a lot and it doesnt happen at all?
