I have been on the combiend pill for a year and have gained 10kg, how long does it take for the weight to drop off once i stop taking the pill?

Don't know: it is impossible to predeict how weight will come off. Taht is a lot of weght but you put it on at a time in your life that lots of teens put on weight. it may not be related to the pill. Read the book "The Protein Power Life Plan" by Eades for a diet and get in an exercise program to get your metabolism revved up. You may be able to stay on the pill and lose weight. it is hard to predict

Don't stop: Don't stop pill to lose weight. You can lose weight now just as easily. Count calories. Slim-Fast recommends 1400 calories for a person 5'4 with exercise. That's about right, but without exercise 1200 calories works too. (adjust a little up and down based on your height (up or down), at 100 cals per inch (up or down). If you learn to watch calories, then you will always be in control of weight.
