Is this normal?

30f. I’ve been finding that my tolerance is just not what it used to be. In college, I could have 10+ shots in a night, get the spins, maybe a little nausea, but was all fine. Wake up in the morning and go to the gym.

Now, I have 4-5 drinks MAX with friends and I am experiencing cold sweats, waves of intense nausea and fast heart pumping waking me up all night, and then in the morning, puking 🙁

Whats the deal?

I know alcohol tolerance goes down as we age but damn this feels excessive!

Basically I’m just asking if this is normal or if I should look into other causes.
