Hi , I have been fighting a sore throat and sinus problem for the past three weeks and just can’t get my blood sugars down . I’m eating properly and exercising. I’m type 2 diet controlled . I have been taking OTC meds to help with these infections . When can I expect to see a change in my results ? . I am due my annual blood test for Hba1c and really don’t want to go and have it as it will be a false reading as I know that Sudafed can raise blood sugars !! Any advice would be great xx thank you
