Excessive Throwing Up Each Time After Drinking

I am not sure where else to ask but maybe someone in this sub may know.

I am not a big drinker. I only drink on social occasions and that’s about twice a month, maybe less. Each time I drink, towards the end of the night when I’m in bed, I end up throwing up. Some times I just get:

Lil buzz going: 1-2 tequila soda(s)

Good buzz: 3-4 tequila sodas

(very) rarely get trashed: 4+ tequila sodas

*I don’t drink beer, mainly stick to liquor when I do drink, but same thing happens when I drink beer*

Usually an hour or two after going to sleep, I wake up with the feeling of needing to throw up/ make a #2 (sometimes both). I throw up and see chunks of what I’ve eaten throughout the day but the main reason I am making this post is when I go back to bed, I wake up an hour later to throw up again and this process repeats usually 5-6 times. By the 3rd time, it’s just bile that’s coming up.

I know this isn’t normal but a handful of nights ago, I got a lil buzz going and ended up throwing up the whole night until ~7 am.

Any idea what it could be? Allergic reaction? Low tolerance?
