Hey,
Is the problem that you can not force yourself to study for that exam? If that is so, then I could recommed trying to go somewhere else to study. I can't force myself to study asweall, when I am home, where there are so many distractions a hand distance away. For me going to the library help. If you go there without a cell phone or a PC, then internet distraction should be a problem, and the other 2 things shouldn't be an option in a library. I have found that this works for me, hope it helps!
