Btw and while you're at it you could write a post about those patients who feign illness, i.e. pain, to obtain Entonox and/or morphine cos I am fed up with them (they tend to haunt me I guess). I'll never forget that 22 stone guy who tried to convince me and my crewmate that he suffered from sickle cell disease (yeah, right), except he was white, Irish and aparently "caught the virus" while visiting his uncle in South Africa. After that job one could have thought WE had been consuming Entonox as we couldn't stop laughing for an hour or so *lol*
