I have no alcohol - Help!

[nofsky]

You should still have it, are you sure you didn't just overlook it in your inventory? If not you'll probably have to load an earlier save.

Or you could try editing your savegame, it's just a plain text XML file. Look for the alcohol in an earlier save and copy/paste it into the save file. Not sure how well this works, though, I've never tried it myself.
