This is another example of how doctors don't tell you everything but they want you to take their recommended pills. After bladder repair surgery, I started on incontinence pills, and sat around the house all day taking naps. When I complained the doctor thought I was ungrateful, Many years later I quit the pills because it was causing constipation and pain after my spine surgery. When I was diagnosed with beginning levels of type II diabetes, nothing was said about the incontinence so I bought larger sanitary pads. After studying the matter in a college class, I decided that it would be reasonable to expect the metformin to increase urination, to get rid of the sugar. Besides, I was taking a water pill for high blood pressure as well. I bought heavier pads for nighttime use. It is sometimes a tradeoff. The metformin lowers the blood sugar overnight, and I get up three times a night. That's pretty good for an old lady of 84. I need to drink more water and if I don't, I get leg cramps in bed in the morning. It seems we can't have it all. Losing weight helps, I believe. Dorisena
