Hi all. Quick backstory: Age 21, CFS and MCS entire life with many other health complications. Currently unemployed, out of college. Full time healing. I started the Freddd deadlock quartet more than 1 month ago. After a month of no real "big" improvement, I decided to try a old trick I learned at a seminar. Methylcobalamin made me feel MORE TIRED after taking it, at any dose (100mcg-10mg). Opposed to this, the other 3 deadlock quartet's made me feel relatively good after taking them. After researching on the internet, I found that many people have the same experience as me with meb12. So I decided to treat it like an "allergy" or an intolerance. I used a method similar to NAET that I learned from an alternative doctor. In my opinion it works far better than NAET. After doing the allergy eliminating method on the meb12 I could immediately take it without feeling tired. This time around, I actually got a boost from the Meb12. So after ramping up my dose to about 5mg meb12, I finally experienced "overmethylation" from the meb12. I never has previously experienced any overmethylation from meb12.. I know what overmethylation feels like because I experienced it with folate and adob12. After 3 days of feeling quite crappy -what I think to be a healing crisis- my energy started rising to levels that I couldn't achieve before the desensitization. It has only been 5 days since and I am seeing a great increase in well being. This may have been the missing link for me. I will post the process on how to desensitize if it is requested. I will also show how to test for intolerances/allergies using applied kinesiology. Here is a short youtube video of me talking about it.
