Ease up on Caffeine
Whether your drug of choice is diet cola, dark chocolate, or skim lattes, it’s time to pull back. Caffeine lingers in your system for up to 12 hours, so that 3 p.m. java can still have a hold on you come bedtime. When coffee cravings hit after noon, reach for a cup of decaf, says Phyllis C. Zee, M.D., Ph.D., the director of the Sleep Disorders Program at Northwestern University. If you’re desperate for an energy boost, try going for a brisk walk around the block instead of drinking that cup of joe.
