Why don't you just take some B supplements. Her shots sound expensive and focused at weight loss.

Start with a B-50 complex and 1000 mcgs of B-12. You might consider B-12 drops if you are concerned about absorption. B-12 and folate are common blood tests. I'd do the blood test before getting the injections. You want B-12 to be about 1000 pcgms/mL and about 20 or above for folate. These supplements should show result rather quickly.

From what you say about your exercise and such, why are you seeing the NUCCA ? Do you have head aches ?

You are doing great. Get the B's going and see how you do. I bet you do great.

My best to you.
