How much time before or after the SWFdid you drink the extra water? Too close and it could be diluting the ratio of the saltwater mix (2 tsp per 32 oz). If not mistaken Birkham Yoga is the one where they turn the temps up in the room and you sweat lots right? That being the case you would be loosing lots of fluids and the main cause for the SWF to be retained is dehydration and the system trying to retain all fluids. You might not be trying enough to drink more water. How many lemonades are you drinking per day? How much water? Are you using the cayenne as per the recipe or more?
Weight loss is irrelevant as thie MC is not a weight loss diet and the body will do what it needs to do the most to heal and cleanse first and this can vary tremendously from person to person depending on many factors.
