Second adjustment and bottom braces!

So I recently had my second adjustment, which went fine. They just adjusted the wire a bit and fixed the coil springs :). They also took a mould of my bottom teeth for my bottom braces. Aaand then I went back 2 days ago to get my bottom braces on. So far I hate them! They're so painful and I have about 5000000 ulcers in my mouth from the brackets rubbing. Not to mention my throat seems to be slightly infected. Butttttt it's all worth it in the end. Only 18 months to go!
