I’m put off drinking Help!

So maybe 3 weeks ago I was drinking having a good time but I fell sick. Not from the alcholol I just actually had a sickness. Anyways that night and the next 2 days were awful. I recovered but since the thought of drinking is so off putting but I wanna get drunk tonight. I’ve been sick from the alcholol it’s self as well before this and it never put me off I have vodka and really wanna get drunk but the thought of drinking it just makes me feel uneasy. Idk why any advice
