Question,is it ok to drink a protein shake before going to bed????

I have done it when I didn't eat much for dinner and felt like I needed something.. better than junk food so depends on how much sugar or calories I suppose. I sometimes make my own with muscle milk powder and almond milk , throw a few strawberries or frozen banana and you have a good Protein smoothie. I would discuss with the nutritionist if you have one as to whether you are really hungry or just out of habit eating something at bedtime.
