I've used and abused tobacco in one form or another since early teenage-hood. (A long time.) Ditched the cigarettes ages ago, but I still use enough chewing tobaccos to have a pretty high tolerance. It took me by surprise when, a few years ago, I smoked a Partagas Black Label and got put on my ass. I've learned, since, about having something in your belly and/or a sugary beverage, but haven't gone back to experiment. I did have a similar occurrence not too long ago though. I love the JDN Antonia, but I definitely got a bit "heady" from one of the Dark Corojos. I have a few of those left in the cabinet, so I'll give them a try again, now that the weather is finally breaking.
