1. Pace yourself: Keep going, but don’t risk overtaxing yourself. Instead of burning through all your battery life in two hours, spread it out between morning tasks, afternoon tasks, and evening activities, with rest and meals between.
2. Take a walk or a nap: However, if you have trouble sleeping at night, napping can make the insomnia worse. If that’s the case for you, get moving instead. Get up and walk around the block, or just get up and move around. If you are not an insomniac, enjoy that 20– to 30–minute power nap.
3. Skip most supplements: There is no evidence that they works

• DHEA: There is no evidence that dehydroepiandrosterone or DHEA offers any real benefits.
• Iron. Iron only improves energy if you are clearly deficient.
• B vitamins. It is true that B vitamins (B1, B2, B6 and B12) help the body convert food into the form of energy that cells can burn, but taking more B vitamins does not supercharge your cells.

4. Fuel up wisely: A sugary bakery roll delivers plenty of calories, but your body tends to metabolize them faster, and then you can end up with sinking blood sugar and fatigue. You’ll maintain a steadier energy level by eating lean protein and unrefined carbohydrates. Try low–fat yogurt with a sprinkling of nuts, raisins, and honey
