Come on... Who is responsable for the whole history? LOT serving you too much food in the lounge or was it your greed to maximize your lounge visit? Then almost missing the flight and now such a drama?
I fully understand the flight crew! Sure, they cannot judge how bad your body condition was, but of course they want to be on the safe side, avoid an medical emergency on board... And think about how happy you would be if somebody like you - that just got thrown up - would sit down next to you... with a nice sour smell / breath...
Just take this incident as an experience learned (and paid) and try to exclude that it will happen again... It's just your behaviour that you can control by your own!
