You have no idea who I am. I could be a pretty smart guy for all you know.
History repeats itself because of people who think they are above it. What you say here worries me.
Be careful. You are a citizen of the echo chamber now.
The culture of hacker news-type thinking can be very toxic and lead to such thoughts as "I just wish there was a better way to figure out your deficiency than just popping some pills and wait to see what happens. A weekly blood test for vitamin levels combined with mood and health journaling would probably give me the kind of data I'm looking for, but that only seems to be available in science fiction so far."
Notice how you are trying to find a solution based around technology. Why does the solution have to involve technology? I think hanging around on forums like this, or with engineers to often can blind us to solutions which don't require engineering.
If all we have is hammer then nails nails everywhere!!
We're all guilty of it. Let's just be aware of it when it happens and move on.
Ready for the solution? It's very simple but tough to follow through with : Radically Change your diet.
Eat plants mostly, eat within a time window (don't allow yourself to oversnack, etc.), don't eat shit, not even a little bit, cut it out 100%. Be extreme, this is the experimentation phase. Later you can be less extreme, but let's see how much a radical change to the diet will affect the body.
This isn't a guarantee to fix vitamin deficiencies, but I will gladly bet that it will sure help a hell of a lot.
Finally, I would like to add that another trap that we all fall into is trying to optimize a system by changing one thing at a time. Firstly, this doesn't actually work. Secondly, this is extremely slooooowww.
If we want to experience change fast we have to be radical about changing our habits. If I am experimenting with anything in my life it's a good idea to try all sorts of different stuff. Diversify my experiments. Explore. If you are having vitamin deficiency issues and are not setting yourself up to be in the position to explore and experiment with diet, then you will have to wait for luck to come along before your issue can find itself a solution.
Again, hopefully I don't sound like an ass, I am just trying to help, given that I make the same mistake a lot in my own life, and have screwed myself over too much to not try and speak up a bit on the subject.
Feel free to be angry with me :) :(
