One of my favorite expressions about one's low tolerance for alcohol was said by poet, Ibn Linkik: "Imagine that I pass by a vineyard in my vicinity, and I almost topple over whenever I pass its gate".
"فحسبك أنّ كرماً في جواري, أمرّ ببابه فأكاد أسقطُ".
"فحسبك أنّ كرماً في جواري, أمرّ ببابه فأكاد أسقطُ".
