Hi all, I'll try to keep this brief; as many of you know, it's very easy to get carried away when describing your experiences so I'll try to get to the point. I'm a 28 year-old male; I've had health problems since I was 15. First, it was digestive, then, fatigue. I crashed 8 years ago and have been battling since then. A flurry of effective treatments - cold showers, pantethene and adrenal glandular extract (the last being the most important by far) - have more or less given me a normal life. I am studying full-time in Japan, going out with friends, and for the most part doing what I want to. I've viewed this as primarily an adrenal problem for several years now, and have seen a few physicians for it, but mostly self-treated. However, the hallmark symptom that separates most of us from healthy people - exercise intolerance - is still there. I can't lift weights. I can't do Jiu-Jitsu. These things were important to me, but they're off the table now. Anything that gets me sweaty, blood pumping and gasping for air, causes a mild to moderate crash. I've made tons of progress but I just don't have enough in the tank for that. I accepted this for years as just part of my life now, but having stumbled across the methylation protocol, I'm feeling hopeful in a way I haven't for years. It just makes sense for me in a way that the literal thousands of other explanations out there haven't. In fact, I remember that I was taking what appear to be the two main supplements - methylcobalamin and folate - in this supplement for years. I stopped taking it right before I crashed 8 years ago. I recognized that at some point, and I might have tried reintroducing it, but I don't think I stuck with it. All my supplements since then have had cyanocobalamin and folic acid, as far as I'm aware. I never really gave any thought to the idea that they were substantially different. But now I'm onboard. I've ordered the B12 infusion and it's on its way now. I think I should give this a shot, but I also feel like I should ask for someone else's input first. Does it sound like I'm on the right track here? Can I safely proceed by simply trying some of the B12 and seeing how I respond to it or should I do some testing first? I've gained a lot of ground, and I don't want to risk losing it. But at the same time, the thought of recapturing something resembling my old life excites me in ways I can't quite put into words.
