Find it hard to put the right amount of Queal in the water, it's very counter intuitive. Also it f**** with my hypothalamus I am often full but "hungry". same 3 hours later i want to eat even though i don't need it. the bottle is quite big (i never fill it more than 60%) and that adds to the i eat nothing effect. Apart from that great added value. quick, healthy and relatively easy, tastes not too bad, would benefit more tastes, maybe salty ones (or is that too weird to drink?) Apart from that, good taste
