no i'm a healthy 21 year old wanting to do this 40 days. if i can actually start. i was going to start today but cheated so that doesn't count. starting it is the hard part. once i'm done with day 4 i'm on a roll. well tomorrow is definitly it. the only problem i had before durin my 10 fast was numbness on my chest. left side of my chest. i don't know what that was about... but i'm going to finish 40 days. hope you get to do yours too.
