Thanks for your comments folks, brilliant as usual!! I know what you mean about just stopping and starting again and about PhDs usually running over so maybe yeah, just starting again as a first year wouldn't be a problem. I suppose I was worried about the whole thing taking an extra year re: getting work, and about the expense of paying for it. I guess also I could go full time for a year if I needed to. Just worry I suppose, stress etc. Your comments have helped pull me back down to earth.
