Annoying writing problem

I'm really struggling with this book. I don't just mean all the normal struggling of trying do the improbably by writing 50,000 words in a month where I am going away from the computer for several days, or a month in which I struggle with a brain trauma, I mean a problem that I think has been brought on by writing scripts.

It's not hard when you've got two people talking but in many of my scenes I have three or four people talking. I don't want to say Xodiac said every single line but I don't want the reader to get confused either. It's very hard for me. Maybe I should err on the side of too many identifiers. After all it could only help my word count, right?
