After much research, soul searching and advice, I am going to start taking 500mg once a day a dinner. Although my sugar is under control following a low carb diet and exercise, there are to many benefits of the low dose to ignore. With my genetics and seeing what my mom has gone thru, I have been determined for that not to be me. As a cancer survivor and just having another scare, the anti cancer benefits alone helped with my decision. I plan to continue what I have been doing and only take this small dose as hopefully added protection from long term effects of diabetes. My goal is to never be insulin dependant. People always say they hope to come off od meds someday and that is me to but I have decided a big part of that for me is pride in knowing I did it on my own. I can't let my pride get in the way. I don't plan on taking more and the benefit from this low of a dose may be minimal, but that's where I am at for now. Thanks for all the input.

It was a very painful decision. My a1c was stuck around 6.7 with diet and exercise plus losing 30 lbs. Low carb on top of exercise got it to 5.9 in 2 months so if I had waited another month, it probably would have been 5.5 or so. Which is great, but low carb is hard and my dr says a small does of metformin will let me have a piece of bread every now and then. Plus since I have such a family history and it being a progressive disease, she thought it would be better to keep it lower now. Plus she said, and I researched, there are alot of other benefits they have discovered. Anti cancer effects for one which is huge to me as a cancer survisor. Plus it is a little bonus on my lipid panel. Not sure how much 500mg will make a difference but I didn't want my pride of getting it down without meds to do me in later in life. Life happens, I may not always be able to exercise like I am or eat low carb. That's my story. We are all different.
