My doctor has me on metaformin (500 ER)for night time taking and I take my hypo medicine in the morning. I opted to take my Vitamin D at night with my metaformin I did the low glycemic, weight watchers, Atkins, etc. before I was diagnosed with the metabolic disorder and did not see any weight loss results. I was in the gym everyday for 2 hours and still saw no weight loss. This went on for about 2 years or so. I decided to change my direction and push harder to find out what was wrong with my body. I got on the metaformin, Vitamin D with my hypo meds. I lost maybe 3 pds until I read the Thyroid Solution Diet. This diet is a low glycemic approach that incorporates the Mediterranean diet as well. My second lab results came back in 4/13 and my A1c is excellent, thyroid excellent, Vitamin D excellent, Cholesterol at 201 ( I need to watch this) and I feel whole now.
What additional medication are you taking?
I, too, was recently diagnosed with pre-diabetes/insulin resistance and metabolic syndrome (you might want to look into that). My doctor has not put me on any medication for the pre-diabetes; we're trying to do it with diet and exercise.
I'm "lucky" in that I've never been real big on sugary food, so giving it up isn't really a hardship for me. I try to do a low glycemic diet, which prevents blood sugar spikes and the resultant insulin spikes.
