I only found this site yesterday, its very nice to hear from other PhD students considering whether to continue or not. I'm about a year and a half in, but my interest has been on the slide for half a year, and it doesn't seem to be picking up like it did in year 1. I'm seriously considering calling it a day, but as Angie81 has pointed out: to do what? Will i get a ref. from my supervisor? Lots of questions and no answers.
