Gatorade after boxing workout

Lets say I, due to job and other stuff etc., have to train/spar in boxing late at night. My training sessions would get over with at around 9:30 pm. I than plan on drinking a small bottle of gatorade to replenish my fluids and to get some carbs in me. Than when I get home I have my bedtime shake at around 10:30 pm which consists of 55 g of protein with a tbsp of flax.

Is that ok? Or should I get another pro/carb meal in me before my bedtime shake?

Is the gatorade enough for me right when I get done boxing?
