I was feeling down and out for a few months because I was hit with EBV and couldn't do much of anything but rest. I have Hypothyroidism with mild adrenal fatigue. Before I was hit with EBV, I was decently healthy. I was taking glutathione supplement and NAC, high doses. I was hit with EBV at that time, I used to feel bad on that concoction but I just kept doing it and thought it was die off or something like that. Could I have made myself sick from that? Fastforward to recently and I was feeling low on energy and motivation. I took NOW brand Cyanoconbalamin b12 500mcg, Folic Acid 50mcg, halved the pill. That day, I had the worst insomnia and racing thoughts I've ever had, with tiny anxiety. Felt awesome for the whole week the next day, lots of energy and motivation. That feeling went away and so I wanted that feeling to come back but without the racing thoughts, so I tried mb12 500mcg. Got the motivation but lots of anxiety, heavy head feeling, cant concentrate and its been persistent for a couple of days. I definitely have a problem with methylation because of high doses of NAC, any thoughts on how to go about doing this protocol?
