My doctor is trying me on Phentermine to help my metabolism because I've been eating less but still not losing weight. He warned me that I might have to adjust my bolus amounts. I have lowered my carb/insulin ration twice in 3 weeks and am still having lows, even at night when I'm not eating sometimes! I don't know how this drug does it, but it is lowering my insulin requirement. Anyone else have experience with this drug?
