So then expect a long wait to raise your levels and then see results. I hope you are using the active methyl form of B12 and not the cyano. Some people cannot methylate cyano version to its active form so it will work.
You must take it on an empty stomach, as presence of food impairs passive absorption in the intestine.
The new cutoff for "normal" now is recognized as 400. So you are well below that.
Only about 10mcg will be optimally absorbed orally from 1000mcg oral. There is a study that measured this:

For people with long term low B12, faster treatment makes more sense. You don't just need to bring up a level, you need to replenish all your tissues.
But it is your decision in the end.
