I recently completed an 8 day fast and felt great.
On the start of refeeding I only drank fruit juice the first day and got really bad diarrhea. It was so bad I actually think I might have gotten a hemroid from it.
I was so panicked that I threw myself off that the next day I stopped the juice. I ate a Watermelon and an orange and felt fine but I was still so worried about my diarrhea that the next 2 things I ate were banannas.
Now its the next day and I am extremely bloated and don't feel like pooping at all. Nothing hurts but I am really worried I did some serious harm.
