Does Gold Standard or other protein powder brands make a dry version of casein protein?

I have been taking Gold Standard 100% Casein Protein shakes and hour before bed for the past 5 months and it has been working good, however I am trying to cut down on liquids before bed as I drink a lot of water throughout the day. Is there some kind of low carb casein powder product or substitute out there instead of a shake? Im 19 5'10" 152 lbs
