How can you make Christmas less exhausting ?

Each year isn’t fun with insomnia coupled with buying umpteen presents and wrapping them, fighting traffic and cooking/cleaning/cleaning up. I know I’m not alone, right? Everyone is exhausted and frazzled, right? How can this be changed? Do you have any little secrets or methods to make buying for twelve people less deadly next year? If I just sent checks like some do, there would be no gifts under the tree. The four foot tall tree I downsized to this year which makes me feel guilty and lazy.
