How can I make myself less desensitized to alcohol?

When I first started drinking it was great, I loved the happy, care free feeling of being drunk. Now when I drink it’s like I get all of the physical affects of being drunk, like not being able to walk in a straight line, but mentally I’m still the same, I don’t feel happy or more social like I used to. It’s as if mentally I just remain the same way I am when I’m sober, no matter how drunk I get. I usually drink wine, but I’ve tried drinking other things too to see it that helped but it’s basically just the same thing no matter what I have to drink. I’ve also tried taking a break from drinking but then when I go back hoping it will have gotten better it’s just like it was before. The last time I was drunk I had nearly 2 full bottles of white wine and I felt no different mentally than I do when I’m sober. How can I fix this?
