How long does it take for metformin to start working on blood sugar?

Question

I have a question for a friend who has just started a medication for diabetes (Metformin). I would like to know if the effects of this medication are "instantaneous" or if it takes a few weeks to see the positive effects (e.g.: less fatigue, less irritability, etc.). I would like to know if the effects of this medication are "instantaneous" or if it takes a few weeks to see the positive effects? By positive effects, I meant calming the symptoms of hyperglycemia (fatigue, irritability, etc.). thank you
