I found I could move my head without it trying to move back . I picked up the bottle of Gatorade , nine - tenths full , from where I left it the night before when I had drunkenly decided to drink something before bed , and then drunkenly forgotten all about it . I drained it now without pause .

Question: How did the narrator feel after they finished the drink they left next to their bed ?
They felt better as the beverage was able to hydrate them and help with their hangover .
