How to get over/rid of taste aversion?

I’ve always drunk my alcohol neat, in shots. I usually always drink vodka or tequila. A few nights ago, I took more shots of vodka than I should have and was hungover. Maybe two nights later, I drank a few glasses of wine and then did some shots of tequila and again, was very hungover the next day. I tried drinking again last night but could barely get a shot of vodka down before feeling like I wanted to throw up. Even the thought of hard liquor or the smell of hand sanitizer makes me want to gag, with wine being the only thing I could possible fathom drinking.

Is there any way to get over this? Should I just take a break for a while? I don’t like mixed drinks or cocktails so I don’t believe I can try to drink that way. What should I do?
