I am feeling quite nice now almost 2 hours later.
It is physically sedating, slightly dry mouth. Vision blurred slightly too.
Mentally, I feel a bit "stoned" but energetic, slightly euphoric and stimulated.
I can feel the giddiness deep inside, but it is late at night so I am relaxed and content. 
There is a trip report on Erowid written by an experienced frequent user of Nutmeg.
It's almost an FAQ. I'm not going to try the coffee preparation though...

From what I've gathered : if you stay hydrated and find a good dose you will increase your chances of having a positive experience.
The Oil seems to be working! Very mild. I am getting Nutmeg burps, but it isn't unpleasantly strong tasting.
I am very optimistic about this approach and I will try a larger dosage soon.
