Exactly the same for me. The first day I slept a lot, and it really annoyed me having to pull blood-soaked cotton from my mouth then packing fresh cotton back in all the time.
The pain wasn't too bad, but my mouth felt sooo awkward for the next week or so. I could barely eat and I ended up losing like 10 pounds because it was so difficult and annoying trying to chew food.
And yes, it's true that everyone reacts differently. One of my friends is a huge pussy, and he was fine the next day. It just depends.
