For example, regular insulin works best if you take it 30 minutes before you eat. High morning blood sugar levels before breakfast can be a puzzle. There are two common reasons for high before-breakfast blood sugar levels. The other is from taking too little insulin in the evening. To see which one is the cause, set your alarm to self-monitor around 2 or 3 a.m. for several nights and discuss the results with your health care provider.
Many people safely reuse their syringes.
However, if you are ill, have open wounds on your hands, or have poor resistance to infection, do not risk syringe reuse. Keep the needle clean by keeping it capped when you're not using it. Cleaning it with alcohol removes the coating that helps the needle slide into the skin easily. Never let the needle touch anything but clean skin and the top of the insulin bottle. Most important, never let anyone use a syringe you've already used, and don't use anyone else's syringe.
