i had gone through your question and understand your concerns. Unfortunately you did not give information about your regular sugar levels with and without levemir, how long have you been sick and how long to wear levemir. But from your question I conclude that you have been suffering from insulin-dependent diabetes mellitus for a long time. Levemir is used to control your sugar levels, but if you will skip once the injections do not have to worry if you keep your calories in your body. Hopefully do not eat that has a high sugar content so that your sugar levels do not jump too high. Even if you still have a supply of sugar-lowering medications such as metformin you can to drink it for a while. I do not think you should worry if you do not have a case history of too high a level of sugar that causes you to unconscious or make you nervous, sweaty. I hope you get levemir medicine again soon. hope this answers your question. if you have additional quetions or follow up questions then please do not hestitate in writing to us. i will be happy to answer your questions. wishing you good health.
