I had braces when I was younger. I also had an awful thing called an Herbst appliance (google it, it's meant to adjust your bite and it didn't work well honestly, it was nothing but troublesome for me) along with rubber bands like you have now. So in comparison to the annoyances of the Herbst appliance, rubber bands weren't so bad at all. They do make the mouth sore after awhile but take some ibuprofen or tylenol and it should help!
