Surg, this is why I really encourage you to find out what caused you to get low in the first place. I can absorb B12, I'm just bad at it. Mudmucker can't absorb it at all. We each have different reasons why B12 got low for us.

If it turns out you are low due to something like celiac disease, it is very important to treat the root cause to avoid other problems.

If you are low because of smoking or alcohol consumption, it is important to decrease them because it's more than your body can handle.

If you've got pernicious anemia, it's important to learn your body's need and how often to get the shots. (oh, man, Mudmucker, I'd forgotten how AWFUL the fatigue was until you mentioned it!)

There are a few other things that can cause B12 to get low, and each has important reasons why you'd want to identify and control it.
