I'm not a woman, no! Maybe I can sue them for discrimination...

As the title suggests, I am at the end of my 3rd year on an MRC phd, with my funding ending in September 2009. I would like to find 3-6 months more money to get me through the last bit of research I need to do to finish phd. Supervisor has no money spare to pay my stipend.

Anyone got any ideas where I can look? Are there UK grants available for this situation>
