Today, 24.04.17, was the first day of school after the holidays and the beginning of the Challenge.
My challange is to drink 2L water a day. I mostly drink water anyway, so that isn't a big deal, but I don't drink two liters of it I think 1,5L or less than that. Usually I have a waterbottle of 1L in school, but most of the time I don't drink everything of it. I will try to do this this week and maybe also after it.

The first day wasn't really hard I drank a little bit more than 2L. Today I drank everything of my bottel in school, 1L. At home I drank about 1,1L.
