I get sick everytime I drink. Why?

Does anyone know why this could be? For example, I drank two steel reserves one night and was throwing up that same night after feeling nauseous for hours, and even into half of the next day. Usually happens almost everytime I drink unless I very carefully pace myself. Sometimes even having multiple mixed drinks I still throw up all night and all day the next day. It’s happened everytime (unless I pace myself) my boyfriend can drink a bunch of twisted teas and even some steel reserves after, and still just only wake up with a headache, same with my cousin. It seems like I’m the only one that I really know that has this problem. I don’t know if it’s from drinking too fast? Or the amount of sugar? But if me and my boyfriend drank the same amount I’d still be the only sick one out of us two. I can still only just feel barely passed buzzed and I still throw up. It’s not like I can’t “handle” it, but it doesn’t help that when I lay down I get the spins and then that makes me start to get nauseous with a watery mouth and everything. I like to drink here and there, but it’s not fun having to limit myself around everyone just because I know I’ll get sick if I keep going. Oh and not to mention it was so bad the next morning I could hardly walk, and couldn’t keep anything down (food and water) my dramatic a** had my boyfriend take me to the hospital. But it felt like that was really the only solution and relief I could get, if not, I knew it would go on for many more hours of feeling like complete trash. I do eat while drinking, maybe not as much as I should? For reference I’m 165 pounds and 5’4 if that matters. Does anyone have any insight to this?
