Proofreading

I'm scanning the proofs of an article I have coming out (the co-written one) and this task has fallen to me. I've been through it once very carefully and found only three errors. Now I think I should do another cursory scan, but I'm putting it off. The problem is that the task puts me to sleep, making my already weird relation to my own work even worse. Whenever I read over what I've written there is always more to do or things to change, but now that it's in proofs there isn't anything more I can do. It's a scary feeling to have it immutably cast in print, like making a final decision about a relationship. I want to let it go.
