I'm not absorbing b12... is there anything other than a shot I can do?

I went to the doc at the end of December who determined that I have a b12 deficiency.. my level was 197 when normal is 200–1000ish, and she described it as “a pretty significant” deficiency.

They want me to come in for b12 shots. I don’t want to. I started taking a supplement instead, and the doc said if I didn’t start to feel better pretty quickly, then the problem isn’t amount but absorption. Well, I still feel like crap after 2 weeks of 1000mcg supplements. So of course, now she’s telling me I HAVE to come in for shots.

But I’m hearing from multiple people that there are tons of ways to get b12 into my body… liquid supplements, even something similar to those Listerine films that you stick on the roof of your mouth. I tried Google, but I couldn’t really find anything.

Anyone have any info on the subject?
