I had the same obstacle my man. You have to cross that lonesome valley all by yourself. At one point you have to stop reading everything on the internet and go on your own fasting journey. Some people experience different things at different times. In my first week I was on fire! Then, on day 8 I plunged into a nausea that went 5 days straight! All those toxins you've built up over your life are being dumped into your colon and blood stream and it sucks. When I started to refeed on the 18th day I emotionally purged and cried for a solid 20 minutes. It was so cathartic. Keep strong.
