I am presently on Day 14 of 21 and must admit that this has been a far more difficult thing than I had any idea. I look like I have been sitting in front of a blow torch and feel the same. The comments about Vaseline and Aquaphor have helped and it is some small comfort to hear that just about everyone finds this a truly miserable experience.
I planned on doing this in January when the it is normally gloomy but this year it has been abnormally sunny and am curious if the sun affects others as harshly as it has me and am also curious as to how long that will continue.
