Yes, the oil is not cheap. Especially at 3 doses per day. But it HAS been life-changing for me. I'm starting to see a few signs that might indicate its effectiveness is wearing off, and frankly that terrifies me. My symptoms are nothing compared to what many of you face -- but they were enough to make my life utterly miserable. I'm hoping I don't have to go there again, because I don't know what else besides B12 might help.
