So far, I am not seeing much in the way of "mental" improvements. In fact it makes me tense and irritable instead, at 50mcg in the morning daily.

So I skipped two days, and now am trying 1/4 tablet 25mcg today. There is a distinct improvement in my weakness however, and arthritis pain perception. I don't really need memory enhancement yet. I do also have some sinus congestion from the 50mcg dose.

Hubby is taking 50mcg daily after breakfast...and seems to be doing his outside working chores more easily (lots of oak leaves to remove from our property). He is working well on the restore discs for our new computer, and so far seems to process this supplement differently from me.
