i found out im b12 deficient and wanted to start subinguals and tried methylb12 (small amount 300mcg for 1 week everyday) and had great sleep but also felt depressed, sleepy, anxious, dizzy and very de-realized like i was dreaming. i felt very anxious. did you happen to have any similar (or different) side effects when you started methylb12?
did you take it for anemia or just for b12 deficiency?
thanks
