Need more info: If be heavy headedness you mean that you are fatigued, then there are many possible reasons.Without more info, it's hard to say. Since you are a type II diabetic at the age of 30, I can only assume that weight may be an issue.With that can come obstructive sleep apnea, a condition where you stop breathing during sleep. Weight loss and/or a machine to help keep your airway open when you sleep helps
