I find that when I'm preoccupied with what I'm consuming and how many calories it has or binging etc that I'm able to forget and leave the mess that BPD throws on my mind. It gets to the point where I don't even remember I have BPD until I have an episode and wonder if I ever really had it. 

I know this isn't a healthy coping mechanism but I find it quells my dissociation somewhat. I just don't know...anyhow if you relate I'd love to hear abt your experience/s.
