I wish I'd seen this post earlier! Hope you haven't given up yet--you can totally do it!
I don't know if you've checked out the sticky at the top of this Forum for MSPI--Stacy put up a great list of things you can/can't have. There have been quite a few of us who have continued to bf our babies with MSPI--I did so for 14 months and while it was hard sometimes to give things up that I love (like cheese), I actually found enough fun treats that I was able to stick to it
Actually, I didn't lose any weight on the MSPI diet because I got totally hooked on eating tortillas with peanut butter and chocolate chips melted in them--talk about a high calorie snack! But I figured I deserved to eat whatever I wanted that I was allowed since so many foods were off limits.
If you haven't already, join in the discussion on the MSPI thread! It helps so much to know other people are going through it with you!
