Hello and welcome to MedHelp's forums. Thanks for your question. It sounds like you have had a very difficult time of it. How long have you been diagnosed? It's important to get this under control as you know. We are glad you are working with your doctor on this. Here is information regarding Lantus https://www.webmd.com/drugs/2/drug-20815/lantus-u-100-insulin-subcutaneous/details. With regards to taking your oral medications and Lantus together, please speak to your doctor. For many patients, as long as you are checking your blood sugar levels, this is fine. But your doctor should guide you in this. Please let us know what you think and how you are doing.
