Common treatment options include lifestyle changes, medication, and therapy.
Diet: it is always important to watch your diet. You are what you eat. Eat what your body needs, reduce refined foods, processed foods and increase the amount of whole grains and fruits and vegetables. Eating small frequent meals goes a long way. Reduce intake of saturated fats; include more lean meats. Choose grilling and steaming over frying and roasting.

Watch your weight: controlling weight to a desirable level of BMI of 18 and 23 is very important. Obesity is one of the predisposing factors for diabetes heart diseases, and reducing weight controls the onset of diabetes and helps the progression of symptoms in diabetics.
Smoking: Another risk factor for diabetes onset, palpitation, sleeplessness.Quitting is the best option. If not feasible, reducing smoking and gradually quitting should be aimed at. Not just diabetes, the effects on overall health will be evident almost immediately after quitting.
Stress management: there is no getting away from stress. Everybody has their stresses but the trick is to manage it well. Whether it is music or meditation or medication or counselling, make sure stress levels are managed. This also helps prevent complications like heart disease and stroke and promotes well-being
