Hows the discomfort today?? Any better after 24hours?
You will get used to it, I know everyone says it and it seems like a stupid thing to say, but eventually you wont even be able to notice your braces in your mouth. I think the grin and bear it thing can be one of the best things to do, once youve scratched the crap out of your cheek it tends to get used to it and doesnt hurt anymore. As your teeth are pushed back you'll have excess wire poking out of the back anyway.
Yeah I'm in the UK, will have had my braces on two years in April, am due for surgery on March 2nd
