Thats a very good point about knowledge. The same has happend to me lots when it comes to accidently ending up in the middle of a conversation after over hearing.
For example i was on the phone too my mum and we were discussing my dad whos depression and anxiety has started geting a lot worse. She said well went to the doctors and they've changed one of his medications around, the anxiety one. The convo went like this:
Me: Oh so his completely off diazepam now?
Mum: No, no it was ..um..valium..and he was taking 2 of those a day.
ME: Oh sorry, yes Diazepam is the actual chemical, Valium is the brand name. Okay, so what have they substituted the 2xmg diazepam with?
Mum: A stronger version of Valium and his to take it 3 times a day.
Me: Interesting. Can you remember the name?
Mum: *sigh* jeez Andrew..umm ..Adivan?..actvan..?
Me: Oh yep. Actavin..yeah thats lorazepam..its a benzodiazpine like valium but slightly stronger initially. Is he on then 2.5mgs or ...
MUM: HANG on ill get the bloody box..*waits*.. yes..activan 2.5mg 3 times a day.. why do you know all this you wernt ever on these were you?
ME: OH um no, i dont know, i was just reading about them a while ago when i was bored.
My favorite is when i go to my GP. We are really close, he has been my gp from when i was 12 untill now 28. And over time ive told him everything. We've established a "dont bullshit me, and ill do my best to help you out" realationship.
Im on 2mg clonazepam and 10mg diazepam atm.. back a year ago i was also geting 20mg temazepam ( Yes i often got funny looks from the chemist coming in with 3 benzo scripts from the same doctor)
And i remember one time last year going in too get my normal and saying hey mark can i try out nitrazepam instead of the temazepam inwas reading on a forum some people found it better. And he goes "Sure.. ... nitrazepam..nitrazepam..*starts scrolling on computer*"
Me: Mogadom
Him: Thats it! MOGADOM! Cheers Andy
Haha good times
