Hi everyone,

For about a year, I was suffering from major fatigue, weak legs, felt imbalanced with walking, trouble concentrating, trouble finding words, etc. 2 months ago, I found out my B12 level was around 240, so my doctor put me on 1000 mcg/day sublingual B12 tablets (methylcobalamin). I just went back to get my tests done (after 2 months) and my levels are now up to around 675. I feel slightly better but the symptoms are still very bothersome. My question is, how long does it usually take for the symptoms to clear once my levels are back up?

My iron levels are normal and I am going to get my folate levels checked as well since I've read all 3 should be within normal range.

Thanks for all your help.
