it sounds like perhaps the nurse hasnt gone through the implications of gliclazadine with you. Perhaps you need to make an appointment with the GP or whoever is in charge of your care and get the to explain about avoiding hypos, when to test, when to eat carbs and how many, how to know if your blood sugars have gone too low. Especially if you drive.
It is very important that you know this stuff. And what your HbA1c is. How long have you been on gliclazadine?
I second this emotion. I would point out that there is an urban myth that extended use of gliclazide hastens pancreas burnout. This stems from the early sulfonylurea drugs that had a bad reputation for this. However Glic is a new generation sulfonyl drug, and there is absolutlely no evidence showing this as a problem.
I was on 4 tabs a day and still being referred for insulin, but then I discovered LC diets thanks to this site here, and as a result I have bought my bgl down to 'normal' levels and cut my drugs use considerably. Yes I did get some hypos doing it, but they were mild and easily dealt with since it was clear my pancreas and liver both still had some life in them and so I was in no real danger of it getting out of hand, But I treated the hypo;s with [ respect+carbs] to make sure. So not frightened but wary and very aware that it can happen. I recommend the Hypo awareness course offered by this site since I had my firsr hypo on the day I completed the course, and was on my way to Boots to buy some dextrose tabs. Serendipity.
But do make sure you test. NICE does allow a GP to prescribe T2D test support but may need some evidence up front that you are in the ballpark for hypo's or have experienced at least one. I bought my own meter and self funded for a while, collected the readings, and could show that where my bgls were previously running in the 20-30 mmol/l range when he last saw me, my diet was now dropping me into the 4-8 range regularly, so I was indeed a candidate for self test. This proof enabled him to prescribe a meter and test strips, and that was 3 years ago. I have used my readings to alter my diet, my meds timings and doses, and reduced my BP and cholesterol meds as well. My GP is very happy that I have regained control and is now very supportive.
