Ya, mixing them both is bad for me... I totally green out.
I think (at least for me...) they potentiate eachother... The clumsiness of being drunk and the stupid head of pot are both magnified, and the head buzz I get off mixing the two just blows me away (in a bad way)... I can handle both of them excellently on their own, but combined it's just WAY too much disorientation, and yeah... I end up greening out...
