Well done on the HbA1c
As
@nosher8355 says - keep at it and hopefully cholesterol will come down.
I've been on Simvastatin for a few years now with no ill effects and my cholesterol was 3.5 last time. I asked if I could come off them but the DN said not recommended. I'm thinking of asking my GP instead.
Keep doing what you're doing
Edit: Forgot to mention I've seen the practice pharmacist a few times now and turns out she's a bit of a diabetes expert. I'm not so confident with my DN's.
