Swelling of severe kindly check your urine for microalbumin to rule out any loss of protien in urine also get your blood pressure cheked. Kindly make a seven point sugar chart that means take before breakfast 2 hrs after breakfast reading Then before lunch and 2hrs post lunch reading Then before dinner and 2 hrs after dinner reading Then any reading when u wake up at night In your case is suspect eye swelling is because of loss of urine proteins and your waking up probably because of high fluctuations in sugar. However if I am wrong and everything is fine you consult a psychiatrist to rule out insomnia (lack of sleep) problem
