Drinking lots of water and exercisinng are good ideas. Also, rid your house of all sweets, so you can't be tempted. You must change what you eat, and the specialist needs to diagnose your condition and advise you to start. Then we can suggest foods which help. Think about drinking water and going to the bathroom often to help get rid of the sugar in your blood. No sodas, no alcohol for now, no orange juice in large quantities. The doctor will suggest the meds, if any, and they may be temporary, such as insulin to get the numbers below 200. Do the walking and drinking now. Don't wait. Dorisena
