"i was prescribed orlistat by my gp as i was really overweight and recently diagnosed with pcos. i started these pills in early november of this year, changed my diet to low-fat (still had the odd treat here and there!) and have lost 25lbs since! the side effects can be unpleasant but only if you don&#039;t stick to a healthy diet. i rarely do much exercise but tend to walk a lot. could not be happier! i have around 4st 7lbs left to lose! the only thing that&#039;s ever worked for me, love these pills and hope i carry on losing!"
