Hi Hun, It sounds like you are very similar to me. I didn't ever gain with bars, but certainly my weightlosses would be significantly less if I had 1 bar each day. When I stopped this, my losses went back to the average 4-6lbs each week. Now I have 1 bar a week and usually have it as a treat on a Friday (admittedly while watching the Jonathan Ross show - the highlight of my week!!! lol) Maybe try having the 1 bar a week and see if it helps. As for the water flavouring, I haven't noticed this personally, but like MrsE says we are all different and respond to the products differently. The only side effect I get with the sunshine orange flavouring is a horrendous cough! Quite puzzling! Hope you find your resolution soon hun. Hugs x x x
