I'm told that i can't take plain water during confinement otherwise the swelling of my tummy will not subside; we are only allowed to take red dates and longan drink. Is this true?

U can't totally don't drink plain water. That's what I did during my confinement and it causes heatiness in my body and when consulted my tcm he said that, during confinement u still need to drink plain water to balance out.
