Accutane question! Super important!?

Im on my sixth month and I'm SICK of being on it. I miss going out in the sun and i hate being pale.. Also having chapped lips and back pains is a killer.. I told my derm the last time i went i only wanted to take it for two weeks and then be done. She told me it was really my choice how much more i wanted to take. And prescribed me a full month in case i change my mind.. I've taken two weeks of it, and im not sure if I want to just go ahead and finish it. Do the last 2 weeks even really matter? And how long did it take for you (if you've taken it) to be able to go in the sun and not burn? Thanks!
