Gemma, I think it gets easier the longer you go. First of all 33 lbs in 3 months is GOOD progress!!
I had problems with cravings at first too. I think I had to train my brain more than I had to train my body!! Every meal I had to focus on picking out all the Protein first and filling up on that. It will get easier. Now, my body (and brain) doesn't even crave that type of food.
