I have recently lost in the past year 5 stone with slimming world and have now come to a plateau where I am struggling to loose weight so decided to start xenical and follow my slimming world diet. I exercise 4 days a week at the gym cardio and strength now will I still loose with xenical if I already follow a low fat diet and exercise. I have taken for two days so far no oily substance or side affects so are they working?? I have read on here some good comments and wonderful stories of people's experience I just hope I can shift these last two stones.
