Thanks everyone for your opinions. I expected these responses as I had my suspicions that it isn't the magic pill that it appears.

This drug is intended to be prescribed for the morbidly obese...being people with a BMI over 40 (which is me ) I was wondering how many people prescribed this drug are actually the intended users. Maybe the side effect would be less severe? My sister was on it and I was amazed. Yes she is overweight but maybe 10-15kg overweight- certainly not morbidly obese.

Basically I was thinking it would be a short term option for me to help me get moving, not as a long term weight loss solution. Part of my problem at the moment in losing weight is the physical difficulyt I have with exercise. I am reluctant though because of all these horrid side effects
