I just wrote a reply and lost it! Grrr.
Rach, perhaps you could look into Cohens (if you haven't already)
I absolutely love it! I started last year but had to stop due to being pregnant. In the 5ish weeks I was on Cohens, I lost over 20kgs. Amazing. All I did was eat food that is in my everyday life... no pills or shakes or anything like that!
I am about to restart with a whole new plan in the next couple of days. The cost of Cohens is around $700, then it is just the cost of your food, which is everyday food anyway (meat, vegies, fruit, cheeses, yogurt etc)
Sassy123 is another cohenite you could chat to... she has had great results. Your DH could follow your plan along with you and he would benefit without the worry of you having to pay for 2 plans. My Mum has loosly followed my previous plan, and has also had great results. Feel free to PM me anytime if you want more info.
