I'm happy it (presumably) worked for you, but be mindful that some people don't benefit from CBT, either due to it being ineffective or suffering from other issues. I've been to several courses, and it's interesting how it spins your understanding of sleep on its head. It's also crazy how fast new things get introduced in the years I've taken it.
I wish I could vouch for how effective it is on 'falling asleep as soon as your head hits the pillow'. It seems others in group sessions find that it's better/restful sleep, but not necessarily instant. But the people I'm usually grouped with have aggressive forms of insomnia.
I would object because of the bureaucracy. It would cost less to make a new one. Then you could do both. And in 5000 years we might get new alien conspiracies about why we have two sets of pyramids in two different times periods.
