Hi and welcome. Yes, steroids are a real problem as they can cause diabetes or make it worse. As far as I know the usual solutions need to apply i.e. low-carb diet, tablets and possibly insulin but I understand once steroids are stopped the diabetes should fade away to leave you how you were before. Are you overweight? Steroids can cause weight gain which, if so, will need serious reduction in carbs and portion sizes; not ideal. Let us have more info.
