Lee Seung Gi, who is currently busy filming MBC's 'Book of the House of Gu', dished out his feelings on the stress of filming a weekly drama.

"Because of filming, I barely sleep," he confessed during his appearance on MBC's 'Entertainment Relay'. "I need to eat a lot of well-being foods, such as eel juice and things like that."

The rigors of Korean drama filming is well-documented, with several actors and actresses actually fainting due to the stress placed on them by the tight shooting schedule. Hopefully Lee Seung Gi can finish his drama safely!
