You've done a full day of work. Now it's 5pm, and the second shift starts — pickup, dinner, homework, bath, bedtime — with nothing left in the tank.
Part of this is just timing. Most people's natural energy dips in the late afternoon regardless of what they've done that day, and for parents that dip lands right when the second job of the day is about to start.
Coffee at 5pm is a rough trade-off for a lot of parents — it can help get through the evening but risks pushing back your own sleep later that night, which just sets up tomorrow's 5pm to feel the same.
Some parents look for something smaller and more precise for that window instead of another full coffee. Each piece of Neuchu has 50mg of natural caffeine, easy to keep in a bag for exactly this moment. You can find it here.
