I hate my braces. When I got them they told me it would only be on the top and it'd be very quick, a year at most. It's been 2 years, they've put bottom ones on, and they won't even tell me when im supposed to get them off. It's pretty much indefinite now.
Also, don't listen to them about the whole "don't eat popcorn or caramel or any kind of candy" thing, I eat that stuff all the time and have had no problems at all.
