Awww Satchi, how frustrating! It is so irritating when your work comes back with loads of comments on it, and you make the changes, and then there are more comments, and it just goes on. I suppose it's best just to try to have faith in your sup and think that for every comment they make and you act upon, it will be one less comment from the reviewers when you submit it! I suppose it probably doesn't necessarily work quite like that, but that's how I like to think about it, because my sup is the queen of feedback! I think we exchanged about 20 drafts of my first paper, but got it down to four for the last paper so I guess things are going in the right direction! Keep your chin up, hope you managed to get some sleep in the end! Best, KB
