I am a new newbie!

I am 5'6" ad weight 205. I want to be down to 135 by June. Do you think this is doable? Should I try and do full fast? Does full fast include Medifast food (like oatmeal)?
This board is great! I have been lurking a lot, and all of your successes are truly inspiring! I am getting married in August, and I want to be a happy, healthy bride!!
