I was on a 14 day Water Fast . I took off work and planned to besides regular hygienic rituals to just chill out even avoiding much TV as I was doing it for mostly spiritual reasons . On day 4 I started to feel extremely tired which I have experienced because I have fasted several times before, my longest being 9 days (water only). The next day it went from tired to sluggish, headaches, nausea, barely being able to intake water. By Saturday (6th day) I was lathargic I could barely pick my self up to shower and woke up with cold sweats. I was drinking about 1 gallon of water per day but felt dehydrated, my head was killing me and I couldn't even keep down any water. I drove myself to the ER my blood pressure which is usually about 98/78 was 148/80 which confused me because if anything I thought Water Fasting decreases blood pressure, my electrolytes were depleted and most concerning my blood Sugar was 39 the nurse told me that most people whose blood Sugar is 39 can't even talk to her because they are seizing or in a coma. I also had extreme acid reflux when I drank water. I am a healthy 30 year old woman who usually exercises everyday except Sunday. I am also breastfeeding Up until now I have had much faith especially in spiritually lead fast, but it was scary that all that I read said kept going but I could have died. I of course broke my fast by an intravenous dextrose injection (sugar) and a saline drip all my symptoms stopped. Diagnosis: dehydration and hypoglycemia (never had before) why did this happen? And where do I go from here, should I saddle back up or is Water Fasting not for me any longer?
