I am new to this website and just found this post. I should tell you I am in the middle of the exact same thing as you. I am on day 26 I think of the water only regimen. For five days in there, I went without any water and my face broke out even more. I still haven't cracked and gone back to soap but my cheeks look TERRIBLE. There are whiteheads and little red spots everywhere. I feel like I can't leave the house sometimes. It's really difficult to get through. I have been posting some stuff trying to find out if anyone went through this. I'm glad to hear you are having the same issue. It's two weeks past when you posted so I'm curious how you are doing.
I honestly cringe every time in the mirror and just keep wondering when I will finally crack and use something.
Hope you are well!
