Questions on Prandin?

Since 9/08 I have been on Metforim, 500mg, twice a day. I had stomach issues from day one but around 12/08 I did better with it. From January through April my life is stressful due to tax season, working long hours, etc. Long story short, my stomach issues returned and my BG control got worse. Previously, I had fasting numbers around 120 in the morning and 2 hr pp numbers of about 140-150. Recently fasting numbers were 140-150 and 2 hr pp anywhere from 160-200. Also, I’ve started testing at night and my numbers have been staying high.

Stopped taking Metforim about a week ago since I knew I had a doctor’s appt this week and wanted to see if it was the Metforim that was causing my stomach problems. I stopped the Metforim and my stomach problems stopped. BG numbers then really stunk. Anyway, after talking to doctor, he stopped Metforim and put me on Prandin. After researching this drug, my main fear is what this drug will due to my insulin resistance. As much as the Metforim drove me crazy, it did help me to lose weight and I still have a lot more to lose. I mentioned insulin and my doctor (internist) said not yet. I’m looking into an endo because I don’t get the feeling my internist would ever suggest insulin to a type 2.

Any thoughts or experiences would be extremely helpful. Thanks!
