Thanks for your response. Yes, I take Metformin (1,000mg). I'm aware of the possible B-12 depletion but stopped taking B-12 vitamins, because of gout attacks. Ever since I started taking fish oil (7,000mg), however, my gout attacks have become more manageable. So I'll reconsider taking B-12 as well as B complex (containing Folic Acid). Last time, though my B-12 was 550, right in the middle of the normal range (200-900), while my Folate was 20. My B-6 was 26, in the middle of the 5-47 normal range. That was all in 11/09, after having been on 1.0-1.5k Metformin for 6 months. So I'll probably have to get that retested in a few months.
My TSH (.75) is low-normal, so if anything, I'm probably hyper, not hypo. My D-3 hydroxy was 85 - that's after taking Vit D supplements after testing initially very low (15). I stopped taking D supplements, since I'm also suffering from constipation and a D overload could exacerbate it. But since I lost 45 lbs., and I wasn't done losing weight by January, all these serum numbers may not be reliable. Now, I'm stabilizing around 160 pounds, and consuming about 22k cal's per day.

(other things can be a cause too, but ruling this out and/or fixing it is important).[/url]
