When I was first diagnosed my numbers were 185. I was super tired all the time, foggy, bad memory. Couldn't even talk properly. I was sick to my stomach, anxious, shaking... blah blah blah. Anyway, when i first started treatment, my first dr was giving me shots and told me to take 2000 mcg of B12 that disolves. I wasn't feeling much better.

I went to a new dr. He gives me shots every month but the dose in the shot is 100 mg. I have also been taking 3000 mcg of Methyl B-12. It HAS to be methyl. I noticed the difference when I bought a bottle of 5000 mcg that was NOT methyl and I slowly started to have my symptoms come back.

So make sure that your dr is giving you a high dose shot and that your disolving b12 is methyl. And go to 3000mcg. It's going to take some time to heal. It's been over a year and I still have days, sometimes weeks when I feel like crap. Stress can cause my symptoms to flare up. Low B12 causes nerve damage, sometimes if it takes a long time before you even knew about the defiency you may have perminent damage. Somethings will heal, some may not.

Good luck. You'll feel better soon I'm sure.
