I'm trying to manage my diabetes type 2. Any advice on how to manage it better. Some days are good, some days are not so good. I feel fatigue, headache, buzzing in the ear. I also just started coughing recently after I yawn for too long.sometimes, just after yawning. I am on soluble insulin and some other drugs ibuprofen, Vastarel MR, clopidogrel, atorvastatin, gastro-resistant Omeprazole, neurovite.. and others. Please help.
