I Have Diabetes 2 For Last 6 Years And Been

I have diabetes 2 for last 6 years and been on medication by my doctor and followed closely, then this past 8 months my ac1 numbers have went down, no diet change, no medicine change no exercise change. so after testing for 6 months she took me off the meds and my glucose level remains normal. why. My family told me I am a lying! But I have copies of the lab work and trust my doctor with my life could their be a another issue?
Thank you, Wendy Zwin
