i know what you mean. its not as bad as it used to be, i think im starting to control it ... well until last week that is! once it starts, it seems to go on for days! when i can feel it happening, ill just take deep breaths, and it'll go in like 20 seconds, but when someone comments on my red face, or actually 'asks' why im going red ... then its even worse! i remember last year when i worked in a shop, i had a queue of like 6 customers, and as i was new, kept getting things wrong, so i had that to deal with, then another member of staff asked me a question, and i just went bright red, and then ofcourse she just had to ask 'why have you gone so red??', i just pretended i didnt hear her and looked away, i was mortified!
