Hi Yvette,
at 11.3 your HbA1c like eiche says is very high, my last test results came last week at 9.1 and ended up with a telling off from my DN and i'm now on 100mg of sitagliptin as well as 2000mg of metformin, which initially made no difference to my levels as of friday I was still averaging 10 mmol/L.
The good news is friday i started carb counting, i cut out all sugars and have stopped eating bread, pasta, rice potatoes etc and in 2 days my levels have now dropped to between 6.1 (on waking up) and 6.8 (2 hours after food). I cannot recommend strongly enough that you start to watch your carb intake very closely (i'm trying to keep it around 20 carbs a day initially until i plateu and will then adjust my carb intake as neccessary)
If your are on the normal metformin tablets, ask your gp to put you on the slow release metformin the side effects are greatly reduced, I put up with the normal tablets for a year and all I can say is it was probably the most unpleasant and miserable year of my life.
Also ask them to prescribe you test strips and a glucose meter ( i brought my meter but have the strips on prescription) some practices don't like doing this apparently and when they do they want you to restrict your testing to one a week as mine did, even as a type 2 testing weekly is pointless as you have no idea how your levels will spike throughout the day.
