I feel like from yesterday the rapid increase in methyl-b12 stirred my system up too much but I appear to be starting to tolerate 3000 mcg better., most of yesterday I just felt completely nuts. I'm also wondering if dividing the dose up throughout the day would be better, the doses also seem to be time sensitive. What I've noticed though is through this is that there is a clear division of different types of energy. Methyl-b12 patches up something almost purely physical but doesn't touch my cognitive fatigue. D3 when it works provides that actual energy I need but under previous circumstances I couldn't get it to work correctly and when I stablize at my new dose level of methyl-b12 (if I don't need to go back down) I want to try it again and some other things under those circumstances. This is unfortunately just a bandage over a much bigger problem but the increase will keep me going for now physically easier. I guess you can use the car engine going with no wheels idea for this situation right now. I'll see how I do at work today, not expecting a horrible one but I'm not looking forward to it either.
