Mine came off mainly on days 8 and 9.. maybe even 10.
it wasn't THAT bad.. but yeah I would cough a lot.. which hurt a ton.. but I never actually coughed the scabs up :S
I read somewhere to eat foods on those days so you can like scrape them off.. so that's what I did.. I had buttered toast on day 8.
it was amazing.
and it didn't hurt too badly
