Hmmm...don't think I suffered anything like that. I did have cramps though...and increased sensitivity to light/bright things. But it was a "step-down" thing I used...not NRT (I don't even know what that is). You get used to the lower level of nicotine, then step down another notch. You can use gum or a patch. I think they step you down too fast, though. I about doubled the time they recommended. Thing is the replacement stuff is expensive...more than the cigarettes. But I got most of mine free from a quit-smoking program sponsored by the company I work for. Maybe they've got something like that going over there...can only hope so.
