I agree with Sally above, about reducing your sugar and carbohydrate intake as much as possible. If you haven't already started to do this, the site has a free 10 week introductory course that will guide you through low carbing, plus plenty of other info on the Low Carb forum (scroll down from the main Forum tab till you get to the Food and Nutrition heading, and click on the subheading Low Carb Forum). Also, it can help if you increase your water intake, aiming for 2 litres per day
It will probably take some experiment to find out what works for you and your body, coz we're all different & what works for one may not work for another, so we can only try it and see, and adjust as necessary.
Hope the cream from the GP helps you; a gentle wash is good advice and makes sense. If there are any other queries or info you need, there's tons of it here on the various forums, and there are usually plenty of willing volunteers to answer any questions you may have.
