Ad,
how's your mum? thought she goin thru the surgery today? my mum always suffer bad side effect after GA, always come out feeling giddy, sick and vomit non stop the whole day, cannot eat anything one, so poor thing, yet i think in my family, she went thru the most surgeries, make sure you prepare some "pao sheng" water for your mum. put the pao sheng in water and boil for 20 mins.
