Gina - Becky just reached goal so I assume that`s why she is asking about carbs. Good for you Becky on avoiding them until now.....smart girl - wish I had waited!
As for the ketosis smell my daughter mentions from time to time that I have an odour and I too catch a whiff sometimes of what I consider a metallic kind of smell though the other day I could have sworn a small baby had thrown up on me! Oh the joys of this journey.
Hope the water works for you Becky!
