fluid intake

Dr requires minimum of 64 oz fluid,  Doe the almond milk in the protein shake and either the decaf coffee or tea constitute part of that 64oz?

yes it does my nut counts regular coffee soup any liquid

On my plan it does. Your doctor's plan may not include those as part of the 64. 

Everything wet and decaf counts

Yes but....

64 oz. is the minimum amount of fluid.  You want to shoot for higher after 4-6 weeks post-op.  Minimum of 80 oz. per day and 100 oz. if you are working out to the point of sweating.
