If you've done it right, yes you'll be totally fine. And if you've done it wrong, maybe you'll die.<br />
Maybe only have a tiny bit as a test. Like a few sips. And if in an hour you feel fine, maybe half a glass, then a glass and then you should know ur fine.<br />
... But this is only a hypothesis. I dunno if it wont just kill you all at once, regardless of the amount of consumption.
Well, that depends
Yes of course if you know how to make it.
