not a scot (actually i'm english - shock, horror) but i was married to a scottish girl and lived in edinburgh off and on for about 10 years, and some things have stuck.

i think that i am processing codeine ok, as when i took some of my late mum's pure codeine tablets (she got them for awful menstrual/menopause problems) it sent me off into a warm nice place. but try getting them from your gp these days, if you are a man.
