Im a bit of a veteran of the old elemental too! I was on it for 7 1/2 months at one point (out of choice) and been on it alot since then!
For me, i call it a miracle, i was days away from the dreaded bag, being very ill and within say a month i was a complete new pearson, and have managed to avoid it ever since! My dietician let me have 'foxes glacier mints' - which were a god send! Cant stand them now tho, ive eaten way too many in my life!
Good luck, it is difficult at first, and then later on too, but once you notice a difference, that for me was by far enough insentive to carry on!
If you can do it, it REALLY is worth it!
