Setting wake-up and bedtimes can help you reduce oversleeping. Avoid daytime naps or restrict them to 20-30 minutes. Create a comfortable but not too comfy sleep environment to avoid oversleeping. Maintain energy levels with frequent exercise and a balanced diet. Use an alarm clock that needs getting up to turn off. If oversleeping continues, see a doctor. Artvigil 150 mg may be prescribed under medical supervision to promote alertness and control excessive drowsiness.
