I am glad that you are feeling a bit better and not giving up. Good signs that you don’t have pink tongue and no Body Odor . I don’t think you need to dry fast now, you need some water to keep toxins moving. But has to be as per thirst. People drink copious amount of water, but that is a lot of burden for the kidneys.
Yes, I would break my fast on day 41. Break your fast very gently. First day water and juice mixed. After you refeed for a few months, you can always fast for maintenance.
