One of those sunrise alarm clocks, going to bed more than 8 hours before it goes off, a neti pot or benadryl so I can breath while sleeping. Blackout shades, and an air filter that makes some soft white noise.
Only problem is my kid sees the light early on and assumes I am already awake. Then he comes and puts a hand on my shoulder while leaning in with the light behind him. Not sure that one will make adulthood. Lol
