Questions about alcohol intolerance

I am someone of Asian descent, and as such I experience terrible flush symptoms whenever I drink. However, I’ve noticed that no matter how much I drink, I feel entirely sober while still getting the hot/red face and racing heart.

It sucks because in social gatherings I basically can’t drink at all, and when I do try I don’t feel any of the low inhibitions or drunkedness as my friends around me do. I don’t think I’ve felt even a little drunk my entire life no matter how much I drink.

Has anyone else experienced this, and are there any fixes?
