Thank you very very much for your suggestions..
Do you think have i to be scared about permanent symptoms of overmethylation ? Now i stopped everythings...
I have never heard of permanent symptoms of "overmethylation", whatever that means.
I am not sure what the term really means. We have discussed it on the forum many times, everyone has his own opinion. Personally I don't believe there is such thing, at least not in the way it is described.
I would simply call them adverse reactions to methyl-supplements. I have had those as well: extra anxiety, jittery feeling, a couple of times really bad adrenaline rushes... etc... not very funny.
It's not really that my methylation was running faster, in fact I did a test at the time that showed I had very very bad methylation. It was probably due to restarting some pathways that had been sleeping for years.
If i deceide to start with only mega dose of B12, do you think i can start with tablet of 5 mg of methylcobalamin 1/day and then increase till 3/days and then add gradually the same dose of adelcobalamyn and after when 30 mg is reached i will add 200 mcg of methylfolate ?
Sorry, I need to reiterate. The words
start and
mega dose, shouldn't be in the same sentence

Unless you have a critical B12 deficiency confirmed by lab tests, why would you start with a "megadose" and risk side effects? Even minor ones?
If you're doing this alone, with no medical guidance, at least be sure to stay on the safe side.
5mg of sublingual Methyl-B12 would have sent me to the hospital with a panic attack two years ago. Injections are even stronger. Now I can take twice as much and it helps. It has taken me 2 years of slowly adding up a little more, very slowly.
Be gentle and gradual and you will likely benefit from this.
Since you already have taken methyl supplements and have had bad reactions, why risking again? Start with a low dose. If you're unsure, start at 100-200mcg. See what happens and add more
slowly, don't just double the dose on every update
30mg of Adeno-B12 is a horse like dose. Plus adeno B12 is not a priority as Methy-B12, if you're looking into helping a neuropathy Methyl-B12 is the most important, and it will convert to Adeno-B12 as well.
Keep it cool
