1000mcg is low for a seriously pernicious patient.
If you hadn't ordered them already, I'd suggest 5000 to start daily. This is of the activated methylcobalamin type for best results.
Also you should take that on an empty stomach. Under the tongue is not necessary, but food will impair absorption.
Why don't you start at 2 tablets daily.
