I think the only utility of taking alcohol this way is if one thinks that having alcohol in one's system would speed the end of life(because it potentiates other substances), but the problem of adding it as a supplement to a regimen is an increased risk of vomiting, basically. You can also get very intoxicated very quickly this way, so... it's something you'd need to take a lot of care with.
One would basically need to know:
1) Is there a vomitting risk with the substances one is taking
2) does alcohol potentiate the substances
