What I did in my 4 day water fast Daily salt intake, I recommend himalaya salt. 2-3x per day 1 pinch Put lemon in your water for potassium Magnesium supplement (optional) It's mainly magnesium, potassium and sodium that your body flushes out on a water fast so yea that's what I learned. The salt really makes the difference. Last time, on day 3 in the morning I felt reall really bad, I stood up to break my fast but decided to try salt first. Ate some salt and drank a big glass of water and I felt perfect almost instantly.

@Jia Ruan I don't put it in my water, I take a pinch, put it in my mouth let it dissolve a bit and drink it away with a big glass

I agree with all comments here. But best thing is being in the culture. To give you context: I have had spanish at school 1 hour per week for 1 year in 2019. So I had the basics, nothing much. Neither was I a good student at all. Last summer I went to Malaga, first couple of days I was struggling with understanding people, everyone seemed to be talking soooo fast. After even like 5--6 days of hearing the language and trying to be involved has done more than what duolingo couldn't have done in 2 months. I started to understand more and more and as the days went by I started to remember the grammar and tenses that I hadn't been in touch with in years, the things I thought I had completely forgotten started to come back. So yea apps are a great tool but best way is to speak the language.

I'm currently on a dopamine detox since 2nd of November and I just finished a 3-day water fast. Pretty uncomfortable if you ask me. It is life changing. Uncomfortable in the short term to be comfortable in the long term.
