My best friend who is also Asian had the same issues. Red, digestion etc. Beer is not for him.
One thing he does now is take Zantac before drinking and it alleviates his issues. Apparently has an enzyme required for digestion that he doesn't naturally produce? I'm pretty sure he had the doctor involved in it.
"The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents... some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new Dark Age."
-H.P. Lovecraft
