Im Getting Braces. Should I Worry if I Have a Large Tongue?

I'm a 34yr male, 15yrs ago I had bonding placed on my two front teeth to close a very large gap. I never liked it because it made my teeth look huge and the coloration is off and now there is a small space now. So I've decided to finally decided to get braces. I'm going to get the clear ceramic ones. I should have them on in a couple weeks. I was always told I had a large tongue/tongue thurst should I be worried. I was told I would have to wear them for 2yrs total cost is 6000.
