Welcome to 3FC!
You're right, this is a good place to find support and advice - there's a lot of experience floating around here.
I think your plan sounds good, but I wonder how well you'll be able to stick to it while in college and a fraternity. I'm just in grad school this fall, and I know that when I was an undergrad it was murder to try and stick to an only-whole-foods plan.
Maybe try a combination of portion control and healthy foods? For example, eat well for the earlier meals in the day, and if you're going out that night save up some calories or whatever to eat some of the less healthy foods and drinks.
I know that when I restrict too much, I do well for a couple weeks and then crash and burn. I do much better if I make it something I like to do (the same goes for exercise), and when I cut myself some slack.
My advice is to work to stay on plan, but if you slip just catch it as quick as you can, and then let it go and move on (but try to not fall into the same trap). Don't beat yourself up over anything - that just makes it harder.
And wow, 30 lbs in 8 weeks? That would take me like 6 months if I don't crash diet. It must be awesome to be a foot taller than I am.
I don't know if any of that was what you were looking for, but I hope it helped at all. Good luck finding and adapting a plan, and congrats for taking the step to get healthier!
