14-Day Water Fasting update
Day 4
Starting weight: 140 pounds
Current weight: 138 pounds

How I feel: Lethargic and nauseous. I wanted to get up and go for a jog today but I can't even sit upright in bed without feeling nauseated. My back aches, my bones ache, my head aches... everywhere aches! I wonder if this is what they call the "keto flu" and hopefully it will pass.

Signs and symptoms: My breath is neither fruity-smelling nor metallic in taste. It tastes rather sour and acidic. I have to brush my teeth (without toothpaste) 3-4 times per day to get rid of the acidity. I am having bad acid reflux from lying down all day. There is a sharp pain in the epigastric region of my abdomen, and it worsens upon burping. My mind is still foggy and I am always tired. I slept for 14 hours straight today. I am breathing faster than usual although my heart rate is normal.
