I was diagnosed with PA earlier this month. My B-12 levels were at 286, and I was suffering from fatigue, exhaustion, depression, and brain fog.

Immediately upon telling me I was b-12 deficient, my Dr started me on 1000 mcg shots, once per week for a month then once per month. That was two weeks ago. I felt great after the first shot, then crashed down before I could take my second shot. Same thing today, feeling like I crashed down (I am suppose to get my shot tonight).

I found this board last week, and after reading about the oral supplement, I add that into my routine this past Saturday. 1000 mcg of Jarrow Methal b-12 as soon as I wake up each morning, then wait an hour before eating.

So my question is: how long should it take before I notice if the oral supplement is working? I am continuing the shots on top of the oral supplements. But my goal is to be able to make it between shots without crashing down. At least that is the goal for right now.

Thanks in advance.
