Today’s day 3 of metformin (500 mg/day). I guess it’s going okay. I feel, constantly, a general sense of unease in the digestive area. I’m bloated, gassy, crampy, and uncomfortable. Everyday, two and a half hours (exactly) after I take the pill, I have diarrhea. I’ve gone from being (almost) constantly hungry before I started metformin, to never, ever being hungry. I’m forcing myself to eat at the appropriate times, even if it’s just a little. I also have a chemical/metallic taste in my mouth in the evenings, which on the first night caused me to throw out the chicken my husband had made for dinner because I thought it had spoiled. Another interesting side effect is that I seem to have lost 4 pounds between Monday and today, which is very nice, although it could just be a fluke or water-weight. But water-weight would seem odd, given how ridiculously bloated I am.
