uhmmm, you could do that, yeah. But it would taste absolutely rancid, if I were you I would just swallow the white half. If you're that persistant you can crush it up and parachute it or put it in capsules. I seriously doubt that you would be able to finish that cup of coffee if you dissolved it in there.
There are actually two coatings on the pill, after you take the white coating off, you can peel away a clear coating from the white part of the pill. Also, I am pretty sure you can cut off the hard white tip at the end opposite from the grey part.
good luck.
