It might be better to up your dose to 5mg a day.
When you are so low, there will be places competing for the B12 so you should give it a higher dose for a while --say 3 months daily.
Also take it on an empty stomach. Presence of food may impair absorption, or give erratic results.
Methyl should work faster. It is the activated form the tissues use. The cyano has to be converted in order to work at all.
There are 5mg tablets so you don't have to take 5 of the 1000mcg. At least that is true for the methyl.
It is not a huge deal about the cyano...since you already used it well. Some people react to the cyanide portion, and some don't convert well, that is why methyl is suggested today.
But I do think you would find better results by using MORE.
