For SAD, daily morning light therapy is a game-changer; I recommend using a 10,000-lux light box for 20-30 minutes, keeping it about 16-24 inches from your face. To minimize jitters, ensure you're well-hydrated and have a light breakfast first. For one client, I had them start with 10 minutes at 24 inches for a week, slowly increasing the duration and moving the box slightly closer, helping them adjust without feeling overstimulated.
