USING SUPPLEMENTS TO REDUCE BLOOD SUGAR

Can anyone help me

I generally use supplements like Cinnamon capsule to lower my blood sugar when they are high especially in the morning but I also use some in the afternoon
I do a 9 to 5 pm job Monday to Friday. These supplements works fine for me during the week in the office but during the weekend in the afternon, they work in the opposite direction. Can anyone explain what is happening . I don't understand why the same drug will work in the office and not work when I work in the house.

I would guess, (guess only, just to be clear) that it has something to do with What you eat during the week compared to the weekend and how busy you are. Most of us like to relax on the weekend and so you will find that you may not be as stressed/ active as you are 9-5 during the week (Or with maybe you are More stressed even!?). Also, maybe you graze more while at work (rather than a larger meal)? This would help keep you bg constant and not spike. Or maybe you eat more carbs at the weekend (comfort foods maybe?).
If you wanted to narrow it down I would keep a food diary for a couple of weeks and make comparison.
