I can't get drunk and I can't drink more because I feel like I'm throwing up if I drink one more drink...?

What's the problem with me?
Update: I don't even eat so much but I also can't drink a lot, just a little bit and then I got this feeling of throwing up.
In the past I used to drink a lot more and not throwing up. The last time I think I drink half a whiskey bottle and threw up but also get so heavily drunk..
But now I can't anymore...
