Thanks so much for your response, mrsD!

I've read a great deal of the B12 thread already and am purchasing the Jarrows brand. I'm just waiting to find out what the blood test results say before I start taking it regularly. My last doctor said it was high back in January of 2012, but I'm requesting those records be sent to my neurologist for my appointment on Monday, and I'd love to know what she actually considered "high," as well as comparing the two to see if my levels have gone down since then. B12 was so low a few years ago that I did take injections once every two weeks, but they stopped when my levels were "normal." Have to say, I never really did feel much of an improvement in terms of energy, even with those injections. Maybe "normal" wasn't enough for me?

And yes, the D2 doesn't seem to be doing anything for me! I was shocked that after nine months of taking a huge dosage that it was still as low as it is. Thanks for the tip on magnesium too! I'll be sure to add that to the list of things to mention on Monday.

RE: Cipro and Levaquin: I remember reading the warning label and being kind of shocked that those were being prescribed for a simple UTI, which is what I took it for every time I had to. It didn't occur to me that those may have caused some of this until I saw someone else mention it on here. I've taken both of those maybe three or four times in the last year. When it was Levofloxacin, I actually stopped taking it after three days and asked my doctor to give me something else, because I felt like I was having terrible side effects. Her advice to me was to keep taking it with plenty of water.

I ignored her. lol

Anyway, thanks so much again for your advice. I'll be taking it, I'm sure!
