I am definitely a fan of Lantus here. It helps with overall control and limits night time hypos. I am on humolog during the day have been since diagnoses 17 years ago and still going great guns with it.
Are you able to book in to see an educator or nutritionist? They can help you identify low GI foods that will help keep you stable and also teach you about carb counting, so you can adjust your doses based on the carbs you eat.
