I agree that 4s are not hypo but I was worried about the poster potentially starting the gliclazide -
@JoKalsbeek said it more eloquently and more clearly
I am sorry that you feel dismissed by your medical professionals. That is very disheartening.
We can't give medical advice obviously. I understand your worry about whether or not to take the medication and worrying each way. And the kicker is that stress and illness already increase our blood sugar levels (and pain as I can confirm at the moment

)
If you decide to at least delay taking the medication you could try lowering your carbs and testing and see what that does to your levels- that would allow you to talk to another doctor and ask for some further advice. You may want specific advice on whether the doctor agrees that it would be okay to delay the medication for a period- say 3 months and get another HbA1c. The regular testing gives instant feedback and kept me motivated at first.
Let us know how you plan to go and how your readings are- people here are amazing and very willing to offer support advice and encouragement.
Virtual hug as well just because.
