Lelouch has his love for his sister (and his friends and such) to keep him sane ;]
Err, for a while at least. Let's just hope it's long enough for him to defeat Britannia! Lulu isn't insane yet, but judging by how insane he seemed when he remembered he had the Geass in R2 Ep 1, I wouldn't doubt that he does loose his sanity by the end of CG (but I really do hope not). He also has the trauma of his mother's death and his crazy family stacked against him keeping his sanity...
