For the effective amounts(mg etc) I truly have no clue. Though my inclination is that the total intake was likely very small given the duration of the exposure, affected area(other than under the tongue) and overall concentration.
That said, there may actually be a calculation for this though I'm not sure. Along these same lines, I know that many of the medications that make use of the sublingual method also contain special ingredients(carriers) aimed at improving assimilation. And so I'm inclined to think your exposure wasn't likely significant.
