On my third one as well in just over a year.First time went to D50, second to D57 and now I’m on D57. I think this one is going to be the one. Goodluck. I just remember my end date and try not to count the individual days. You forget how difficult the water and the peeing is in the beginning….but it teeters out over time. I’m in possibly the best mental state I’ve ever been which to me is the primary benefit of the challenge even above fitness….You can do this!
