I've always looked at braces as some type of Dark Age torture device.
And that, they are, Jimmy. I got mine on in the beginning of August. And I never got over the torment of not being able to eat all my sugary unhealthiness.
Anyway, as for advice, it only hurts about a week, but in the meantime, take some Advil/Ibuprophen/etc. for the pain.
As for the foods, EVERYTHING IS A LIE. Well, not really, but there are some things under those categories that you can still eat. So far, I've eaten whole apples, taffy, skittles, pretzels, hard candy and mints... and I haven't broken anything so far. Same for my best friends. We always go to the movies together, and we eat like gabones. So I wouldn't go binging on stickies, but you can still have a Laffy Taffy or a Jolly Rancher every now and then, as long as your careful.
But, if you want to play it safe, then yeah, limit your consumptions of that stuff.
