Metformin first dose of the day...

Just a quick question today. Ive gotten into the habit the last year of not eating anything for first half of the day most days, meaning ofc im not taking my Metformin either till then. Should i be getting that little white pill in me asap after waking for maximum benefit?

Im currently on 500mg three times a day.

Im aware of all the other reasons i shouldn't be skipping breakfast should i be adding this to the list?

Thanks.
