I know that for monks there are guidelines (restrictions) for eating. Like for example a monk will not eat after noon.
Are there guidelines or restrictions for monks too regarding drinking (by this I mean normal drinking, like water, tea, and not alcohol). Can a monk drink as much as he pleases on a day. Is there no limit? He can drink throughout the whole day if he likes? Or are there rules that say no drinking after 6 PM or something similar?
