My pancreas is damaged due to alcohol consumption, and my blood sugar levels are very high (350-410) despite taking Janumet 50/500. I am also experiencing joint pain, muscle pain, and dry mouth. What medicines should I take to control my blood sugar and relieve these symptoms?

Your very high blood sugar (350-410 mg/dL) indicates Janumet is no longer working. Because alcohol has damaged your pancreas, you likely have pancreatogenic diabetes, which usually requires insulin therapy rather than oral tablets. Your dry mouth is a sign of dehydration from high blood sugar, so drink plenty of water. The joint and muscle pain needs a doctor's evaluation to rule out diabetic neuropathy or pancreatitis flare-ups. Please seek immediate medical care or go to an emergency room to get your sugars down safely. Do not self-medicate, and strictly avoid alcohol.
