How I can bring my A1C down? My A1C was 7.6, then 7.9 and now it's spiked to 8.00. I work an evening shift and my lunch time is not fixed. Every day different. Is that a possible reason for my A1c going up? Sometimes when I come home from work, my blood sugar level is down to 83. I also feel very tired. I should exercise, but I don't because of my night shift job. Please advise me.
