If you're going to do it, I'd open the cap and pour it into a water filled enema bottle. The only downside I see (other than having to do it of course) is B5150's comment about prostate issues.
Alcohol isn't stronger in an enema, it just hits you a lot faster and if you overdo it, vomiting won't help, so you can die of alcohol poisoning easily this way. I've read that the hangovers aren't as bad, but that's probably just because it tears up your a$$hole instead of your stomach lining. No matter where you stick it, it is still going to get processed by your liver at some point.
Besides that, it's usually cholesterol numbers that get all f*cked up from heavy oral cycles, not liver values. I could see more value in using a nonmethyl this way than SD or Hdrol or any of the others (to increase absorption).
