Well, the good news is that the numbness is gone again!

That's pretty consistent with the way things have gone--after the stomach bug, it took about 2 days for the numbness to go away, too. (Although it did take about three weeks of fairly heavy supplementation to make it go away the first time). I started the extra 25 mg of zinc (yay, Jimmy!!) at the same time as the extra 50% of the prenatal, so it's hard to know for sure which one is working, but I'm betting on the zinc! Either way, I'm definitely going to keep them both up.
This is exactly what it says on the lab report: "B12, serum 590 pg/mL (200-1100)" I don't know what you mean by "units," so if there's something else you need, let me know. The only thing on the report that was even close to being below range was on the hematology report. The MCH level was 26.5 pg with a normal range of 27-33 and the hemoglobin was 11.8 g/dL with a range of 11.7-15.5. My blood is always a little messed up, though, because of this benign thalassemia trait I carry that (from what I understand) makes my red blood cells smaller than normal (but fine).
Thank you so much for all your help--I'm feeling more hopeful this morning!
