Trulicity...any tips or suggestions with diet

My doctor wants me to try trulicity for 4 months to see if it helps lower my a1c…currently 7.9… I’m most happy with myself about it… so I am taking metformin er 2 times a day 500mg tablet…numbers aren’t chsnging. I’m still ranging at 200… I just started walking more since the weather has turned nice again… looking at going to the gym slowly. Want to know if anyone has had any weird side effects from trulicity and if it’s better to tske it in thr am or pm?
