I drank a lot water during my first round of Keto. What it did to me was wash off a lot of essential electrolytes which the body has a hard time holding on to due to lack of carbs. Made me miserable. Dr. Berg on YouTube also advised not to drink too much water for this reason so this time around I’m drinking only as per thirst and then ‘a little more’. It’s working for me so far. I’m much more normal. I will do Pranayam which balances the autonomic and parasynthetic nervous systems. Will update if I see results...
