questions on interviewing

So, as I'm going through and transcribing my interview, I am having a lot of trouble writing down every word that is said... I keep missing words that don't normally register such as "like" and "um" when they're in the middle of a sentence, and I've been going thru and listening a second time to try to put them back in, but is that happening to anyone else? Have you noticed? Also, I really am understanding what everyone was saying about hearing yourself talk over the person you're interviewing. There's a few times when I'm in the middle of asking a question and the person I'm interviewing just starts to talk and I miss a few words because I'm still trying to finish reading the question... Does anyone have suggestions on how to avoid that happening in interviews? I honestly didn't notice I was doing it at the time and it's only now as I'm going back thru it that I'm realizing...
