Daytime drowsiness can be treated with lifestyle changes and medicines. Start with a regular sleep routine to increase sleep quality. Maintain a dark, cool, and quiet sleep environment. Exercise throughout the day to enhance energy. Consume balanced meals and avoid heavy or sugary foods that cause fatigue. If you're still struggling, Modalert (modafinil) can improve alertness and minimize daytime drowsiness, but it should be used under medical supervision owing to adverse effects.
