Getting braces in 3 weeks. questions?

I just got braces like 3 weeks ago. My teeth only hurt like the first 2 days but my mouth mainly hurt, there were (are) still a lot of sores. The molds taste really gross, but i lived.. :) it tastes gummy and sticky and gross, ok i didn't think i was going to have problems swallowing while getting braces but sometimes you kinda do. ya again my teeth weren't really sore it was just my mouth, but you get used to it.
