No, I didn't have Ibraces, can't remember what brand I had but they were pretty low profile. And I only had them on top (had labial brackets on the bottom).
Eating generally was a bit weird at first. I think I'd pretty much adjusted after a couple of weeks.
i have ibraces they are great so far the worst bit is the first 7 days then after that every problem you have with them just seems to fade away. My two front teeth had a gap and that closed after 2 weeks
