I have cruised over 20 years as a diabetic type 2. I wear an nsulin pump. First, alcohol stresses the liver. However, i drink rum and diet coke. No carbs. Second, travel with insulin in a bag that can hold a freezer gel bag. I take 150 units a day. I try to regulate it as best i can. Heat and then cold weakens its effectiveness.the only problem is airlines and a melted freezer gel bag. TSA has taken them away. Finally sugar free and no sugar added is deceptive. They still have carbs. These desserts may lots of carbs. Carbs and fat give flavor. Enjoy the trip. My next cruise is the Icon. Lots of walking. And my wife and i will make great memories.
