Honestly, I didn't expect such a noticeable difference. Not only do I have more energy during my overnight shifts, but I feel less irritable and more positive. Even better, I don't feel completely wiped out when I get home, which means I can actually enjoy my limited free time. This has truly improved my daily life.
