Braces coming off early.?

So I've had braces for two months now. I had them tightened for the first time yesterday. They also instructed me to wear rubberbands :( two triangles one on each side 24/7 when I sleep I have to wear one rubberband across my front teeth top and bottom sort of like a square. I've read where it says rubberbands are given when treatment is almost over so do you think after this my braces will come off soon.? I have the Damon braces and I knw they're supposed to work faster.
