How bad does wisdom teeth removal hurt?

Ok, I am having my wisdom teeth removed on June 3; and I am terrified. I will be having all 4 removed at once (all impacted, though the top two are out slightly more than the bottom ones) and will also be having my second molars surgically uprighted. I am really worried about what the pain is like afterwards. I am being put to sleep and know I hopefully shouldn't feel anything during the procedure, but would kinda like to know what's it like afterwards. I have braces as well and before I had them put on, I had to have my 4 first bicuspids extracted which I was equally terrified of. This procedure turned out to be nothing! Any advice will be greatly appreciated! Thanks in advance.
