Oh my god, half of the posts in here are greatly exaggerated!
I got my braces about half a year ago, and first thing I did after getting them sticked to my teeth was going to subway and buying a footlong sandwich.
It was kinda hard to eat, but still it isn't that bad. 4-5 days, then the pain sould be as good as gone.
You just have to get used to eat more carefull if you don't want to bite something off you might want to use later.
The one and only thing that keeps annyoing me is food getting stuck in the braces. Te worst is over after 2 months, but in that time you will have half of the stuff you eat right between your front teeth. It will get better lateron, but even half a year later it still can be annoying as hell if there's something stuck somewhere, and you can't get it out.
All in all, it's annoying, but besides the first week doesn't hurt. Don't be too afraid
P.S.: Don'T get your hopes up too high to get rid of the braces early, since I got them the time I'll keep them has already doubled...
