how to get over sickness an hour into drinking?

I like to drink. Not excessively of course, but maybe once a week I’ll have a couple drinks.

My issue is, I tend to feel sick even after just one. Just straight up nauseous. Last night I had one shot at about 7:30pm, and by 8:30 I put myself to bed because I felt unwell.

I’m a lightweight, I’ll get drunk after 4-5 standard drinks easily. It also doesn’t help that I don’t love the taste of vodka. The one I have right now is Smirnoff. I don’t care that it tastes bad, I’m fine with that. It’s the nausea I get afterwards that ruins it for me.

I’ve only found one thing that I drink that won’t make me sick which is Hard Rated (hard solo).

Any advice/tips/reasonings for why I may be feeling this way so early on?
