Not so much, no. I did attempt to paint a wall around day 16 I think and didn't feel comfortable looking up while standing on the ladder so decided to put it off until I ended the fast. Other than that I felt as normal as can be during the entire fast, although I couldn't get myself to stay up very late and so my evenings would end around 9pm.

I didn't have nightmares but I do remember that my dreams during the fast were incredibly vivid. I never imagined such dreams were possible and it's one of the things I miss most since ending the fast.
