Ha, ha, I'd suggest you stayed away for a few months at least!
With IE, patience and consistency is the key. It must work for you and you must give it time.
I would guess that after switching to diet-free, I put on at least 10lbs (no weighing but clothes were tight and I had to switch sizes for some clothes), which was considerable given that I had not much to lose in the first place. It probably took one year to lose that 10lbs again, all the time fine-tuning my way of eating and what worked for me and what did not.
