From the Carnivorous / Zero Carb Approach section at rawpaleoforum.com, 
some experience:

"ZC is magic. Fat lost, teeth sensitivity and cavities gone, bloating, 
gas and constipation/stomach pain gone, energy extremely high yet very 
very calm and relaxed, physical performance (Sexual and Athletic) 
through the roof. Carbs even in small amounts hurt my teeth, give me 
stomach pains, dull my senses and mood and zap my energy, I hate them 
and will never eat them again."

He didn't mention the constant state of mild euphoria, but nobody is 
perfect.
