HELP! How can I stop my braces hurting?

Hey, I got removable braces yesterday, they have a 2 lumps sticking out on the bottom and top (not that it matters!) There is a set on the top and bottom and all I've been able to eat is yoghurt, soup and pasta! I'm picky so things like scrambled egg I don't like! I also speak funny and can't pronounce my "s" and "k". What shall I do. Please help! ;]]
