Can I drink water after giving birth? Will it cause any joint problem?

I have been told to drink only red date tea esp during the first month. Cant drink water, also cant touch water.. They said it will cause joint problem in the future or u will be sensitive to wind. I normally drink alot of water at least 2 littre everyday for so long, and suddenly will have to totally cut down my water intake. I dont know if i can survive 😅 Any mummies can u pls share ur experience? TIA!
