After a year on herbalife , with the last six months having no weight loss at all, I took the loss of my herbalife distributor as a sign to try something else. As as it was available in my local pharmacy together with health and weigh-in support I am trying Optislim. So far I have tried a meal replacement bar (blueberry cheesecake) and two shakes. One thing that I found with herbalife was that I struggled to drink enough water, so far with this I have been drinking more. I have have mixed the shakes with water (with herbalife I used 1%fat milk) and had normal meals for the other meals, and fruit for snacks. I am keeping track of calories, carbs etc on myfitnesspal. As I understand it I can mix the shakes with milk if I wish and also add yogurt or fruit for variety. i have been walking for exercise and will try to increase this. I don't have anyone to exercise with, and don't really fancy exercise classes particularly since I would have to go alone to any. I have a one one week trial pack of Optislim shakes to see how I go on.
