Headache every day...

Headaches can be a symptom of hyperglycemia, yes.  You need to call your doctor.  Your blood sugar is too high from what you're saying.  Are you taking the metformin and the Lantus on schedule?  Are you eating a lot of carbs? 

Anything with sugar or flour will send your blood sugar skyrocketing.  All breads, pancakes, cakes, cookies, breaded food, food made with flour and food made with sugar.  If you're eating that many carbs, your blood sugar will rise and you'll be taking more insulin and metformin to counteract what you're eating.

I would suggest buying the Richard Bernstein book Diabetes Solution.  He himself is a diabetic (type 1) and an expert on diet and meds for diabetes. 

Be sure to let your doctor know exactly what is going on.  Write down what you eat and how your body reacts.  If you aren't eating a lot of carbs and staying away from the things Lanie mentioned, I'd definitely want to have a thorough check-up. 

 

I just went through something like this.  We were attributing it to high blood sugar but it ended up being an underlying cause that was making my blood sugar get so high.  So, be thoroughly checked out so you know exactly what you are dealing with.
