Taking Dapaglifloxin, last HbA1C test worse than usual, and other effects

[Babooshka59]

I'm Type 2 diabetic, and as I was finding it hard to tolerate Metformin due to digestive issues my GP prescribed Dapaglifloxin, which I have been taking since February. I've also managed to shed 20 pounds in weight this year, despite having a recognised eating disorder (binge eater) and Long COVID, which depletes my energy so I am eating more carbs than I ought just to get my energy levels up. I still need to lose another 20 pounds to get back to the weight I was before my health began to slide, and have been told by the GP practice's diabetic nurse that it is very possible I can still go into remission if I manage that. I therefore expected my HbA1c readings to improve when I had my last test a few weeks ago, but they have shot up since last time to the highest reading ever for me (76) despite the new meds and the weight loss, and also me taking more exercise (about an hour a day gentle walking, in spurts around a private dog walking field). So this increased HbA1c result is disappointing to say the least, and I'm also worried. Have others here experienced similar on this drug? I also seem to be constantly peeing, up to 4 times an hour during the day on occasion, and at least twice in the night. I also suspect I am dehydrated as I find it difficult to remember to take fluids (been like it since I was a kid, I just don't feel thirst) and can't drink much at a sitting. My skin has become very 'loose' and wrinkled looking, especially my hands and arms, and I sometimes wake in the night with a very dry mouth. I'm reluctant to keep drinking more and more (I drink mostly water) as it seems the moment I do I need to visit the loo. I've no idea how much extra fluid I ought to be taking on this drug as the leaflet doesn't say. I'm due a call from the practice diabetic nurse on 28th April, but not expecting much help as I don't feel they are particularly concerned about my situation, and I rarely seem to get any specific answers to questions I raise with them. I'm 65, and was diagnosed in 2018.
