Hi I am a grad student fulltime too and the pre-diet for the vertical sleeve was really hard, but you can push through it, if you can get ahead of your work then do it because your energy is also affected I tried to get some work done before I started and thank God everything worked out. Just plan and plan and stay ahead of your school work any reading you can do now will also help you. I read as much as I could because it was hard for me to concentrate when my belly wanted food and my head could not understand why, once you have the sleeve its a different game I felt so much better I moved slow but dint have the hunger pains..
