Does Glycomet 250 Mg Cause Tiredness?

My father has a fasting sugar of 99. He is taking Insulin and after eating he is taking Glycomet GP 2 . After that he is very tired. Should he have to stop taking Glycomet GP 2 or the Insulin? ## Tiredness can be due to a number of different things, including your father's choice of foods whether he is on insulin or not.

This leads me to wonder if there are any sort of interactions between Metformin and food that might cause it's effects to be increased or amplified. Also, the fact that he is on a few different medications could be a bit overwhelming on his system. If he's able to cycle through...
