I keep getting faster times in cycling/running (fitness going up so as health) and even able to push more weight at the gym (on legs only) despite my frequency being every two weeks injections now. 

So I’m guessing the frequency is enough? I also take regular cofactors and try to not worry too much about “not having enough B12” but deep down I know how much body needed it for so long.

It looks like body is still remyelinating at month 9 and even at this frequency because I get the nerve pressures brief itchy tingling spots in random parts of body or face that feels exactly like when I started b12 recovery which for me was a strong hopeful sign. There has been lots of different wakeup symptoms since the start of recovery: mild itch prickling, gentle pressure, buzzing, tingling etc. 

As a strong marker of resolution, I have been having angular chelitis (abnormal dry cracked corners of mouth) for 8-10 years almost all the time, and it never came back since I started the mb12. 

Same for optic neuritis, an other symptom of the list, that I have had 3-4 times the last years, it did not reappear since starting the recovery.

I’m amazed at how far the body can handle that for so long but also looking forward to keep getting healthier and repair the most possible.

How to know your frequency is enough?
