Having completed a two week trial I did not inject until my stuffy head came back. It was then three days of recovery but nothing severe.
I thought that I might be experiencing shortness of breath at about 6 hours but nothing definitive. I woke up at 11 am with my stuffy head and injected and went back to sleep with no issues.
I have no meaningful information from the past as that is based on less than 4 injections per day.
One thing I noticed is I have developed a habit of evaluating every little thing that is going on with my body. This was developed when injecting less than 4 times a day. Now that I am aware of this habit it will likely go away as it is no longer helpful. It was one of many things that helped me to discover my frequency hypothesis.
I am pleased with the information I got from not injecting for 20 hours although it is subjective. It is helpful for me to have a limit of time between injections although I know that may change one way or the other.
-------------------------------------------------------------------------------------------------------------
Again having just completed a trial I evaluated to determine my next line of inquiry. I let my beginners minds do their thing (after I had ranted) and decided the highest probability of effectiveness was to explore and discover sleep. I might have chosen sleep as I started studying sleep in 1966. What is known about sleep that is meaningful has not changed much and it was not very meaningful in 1966. Most often good sleep is seen as a solution and the cause is never considered. This usually leads to short term solutions that are not effective over time. Most recently CPAP devices. Sleep hygiene was designed by and for office dwellers. I followed that methodology for three years from 1966 to 1968 until I rejected it. So I did not need to study what was thought to be true as I have kept up with the 'studies'
This led me back to my hypothesis with regards to frequency of injections which lead me to maybe it is not best to have less B12 in my blood stream when sleeping which led to maybe that is when I need the most as my body works differently at night and it might be more healing to have more B12 in my bloodstream during the night.
I am using the unproven assumption that my body can heal at a rate that is satisfactory to me if I inject every six hours and more time between injections is not in keeping with my goal of satisfactory healing. This lead to me setting an alarm and injecting every 6 hours. The positive effect was immediate. It has been my experience that an improvement in frequency causes an immediate positive result and then things level out as my body heals.
I reject that EOD is rational for all if patient's if the motivating factor in design is patient outcome It does seem that perhaps the EOD or less works for some it is assumed it will eventually work for all which I reject as being rational or in keeping with a humane standard of care. I am aware it meets the needs of the medical profession and medical facilities.
I discount almost all of the results of my trials of less than 4 times a day.
A small part of my decision to inject every 6 hours was my successful trial of injecting if I happened to wake up more than 4 hours after my last injection.
I have no idea what amount of B12 to inject is best as all my experience is based on the less effective frequency.
I do not find injecting B12 benign to my body with no effect other than more B12 in my urine. I experience changes that could be labeled as side effects. If they go away I consider it a sign of healing although it is hard to experience them.
I am different, I know the effect on my body experiencing injecting 4 times a day. No one that has not experienced injecting 4 times a day is the same in this regards only. This is not a better of worse evaluation it is rational conclusion.
---------------------------------------------------------------------------------------------------------------------------------
I no longer think of myself as lifelong B12 deficient as I recovered without supplementation. I had symptoms of B12 deficiency my whole life off and on and lived in fear of them returning. I doubt I recovered fully but that is not knowable.
I do believe that for reasons unknown my body attacked itself. I believe that my body did so for reasons that are yet unknown. I accept that it might have been best. Does not mean the long term effects are desirable.
I do not accept that severity of symptoms to be a legitimate concept and will not become one until some rational scale of severity is established. It is not helpful due to its subjective nature. All pain and suffering is meaningful.
There is no rational that establishes that PA is permanent and no test that it is or is not. It seems likely to me that with current treatment it is permanent.
I lay no claim to being 'more' rational. I do claim less concern when I can establish to my satisfaction that a conclusion is not rational no matter who made the claim.
I also do not ascribe that any understanding I have will lead to a definitive conclusion. That is one of the ways I use my minds.
Guessing if I used a are you B12 deficient check list it would at this point be negative. That has no value to me as I know I currently need B12 injections in a manner not yet known to thrive in a manner that is satisfactory to me. That is my standard of what works.
If I run out of ideas I think are worth exploring to me I may go over a symptoms list and see which symptoms associated with B12 I have 'cured' and add the symptoms I 'cured' like cramps etc.
Nothing about working with B12 is wonderful. This does not mean I have not had wonderful experiences when working on B12. For me working on B12 is a battle of attrition with no end as of yet.
