I am new to Water Fasting this year. I had planned to do the 30 day but got 2, 4, &5 days three separate times. I'm currently on day 12. Apparently when you feel sick, that's a good sign to keep going. It's your body detoxing. Read the posts from Water Fast in cure zone to get a better understanding.
I've also been brushing my teeth this whole time & have felt hunger up until today actually. I don't feel it right now :) . I have felt really stuffed up, had headaches, cold symptoms, sneezing, my skin has had bumps all over & my face flushed red at various times throughout this fast. Tongue is so white I can't brush it off. Looks like I'm growing a mat of white fur on it. I also had a day where I felt so wonderful and energetic that I hiked 4 hours to a waterfall in the mountains when I was camping. I've learned since that exerting myself on a fast is a bad idea. Still I felt so alive and good to be in the fresh clean air with nature and it was so beautiful. I did get weak towards the end and the next day I felt sick and slept most of the day. I'm down 22lbs 😁though I'm doing it for health as well. Hoping my allergies go away.
