There is less flexibility in liquids during confirment.
During the entire month, I was only permitted to quench my thirst with tea made of red dates. Every night my mother put some red dates, dang shen, dried longan (the fruit of the Chinese evergreen tree) and medlar seeds into a slow cooker.
Throughout the day I had to drink this brew instead of plain water so as to prevent water retention and revitalize health.
My mother constantly warned me about the consequences of drinking plain water which would purportedly make the veins swell.
Was not allowed to open the fridge door during confirment to get cold water as well. but i hear people saying that it is only for the first week. but, my mum insisted that i dont't drink cold water for the whole month.
