What's your experience with gliclazide?

I've been prescribed with gliclazide after 6 months of metformin, low-carb/keto diet and exercise. Long story short, I was able to manage things more or less ok, but ended up loosing too much weight that forced me to stop physical activity. As a result my BG has been slowly increasing while I am trying to recover my weight. After some discussion with my endo, he suggested to try gliclazide but I am afraid it will stress my pancreas and shutdown whatever beta cells are left there.

Whatever your experience is good or bad, I'll be thankful if you share it.
