Metformin
"Metformin has side effects like diarrhea, WHEN I have sugar (regular sugar, fructose and artificial sugar - it does not care). Eat poorly, guaranteed to have diarrhea. Also headaches if sugar spikes quickly, again food choices do this. If I just really want a bite of pizza or candy bar, I eat healthy (lots of vegetables and salad, protein) with NO processed foods, NO breads/pasta/potatoes/rice, and at end of meal have 1-2 bites Savor and stop. I give myself a treat ONCE a month. Keep sugars down to 80-130 by diet and one Metformin 500mg a day. Eat too much at a meal, walk or exercise to burn the carbs. Burn too much and you get shaky or a headache. Water is key too. Water pulls sugar down (dilutes and flushes it out of the fat cells."
