Is the dosage a drop or 1 full dropper?

I made some and ended up with 1 3/4 oz. much more than the expected 1 oz. I used 190 proof liquor. I dosed 5 or so drops almost two hours ago and I am feeling some effect. A friend dosed 2 drops and felt nothing. I JUST reread dosage and I think it is a full eyedropper full. Two for "outerspace".

Also the alcohol is real strong in my batch. It burns when you put it under your tongue. This true for anyone else's?
