Yeah, I offered advice based on what I thought you might need help with, but it doesn't sound like productivity is a problem, is it?

It seems like your problem might be your relationship with yourself or with your studies? I am not sure.

Anyway, my MA is towards more of a humanities / social sciences discipline so I can't relate to the science part of it so much, except in knowing that it's a lot of work, ha.

Regardless, I'd venture to guess that if you did something to change your routine, perhaps you could get some work done... I wonder if getting some new perspective on it might help, too. Meaning talking to people about it, perhaps to your advisor or someone like that? Is there anyone you trust that you can talk to about this?
