I find that during the first few days I have to drink my water luke warm because drinking cold water gives me instant 'goose bumps'. I am like that for the first 5 days or so.
It is really strange, when not on the cleanse my water needs to be ice cold but on the cleanse it has to be room temperature.
As far as the tea, I don't see why you could not drink it cold.
