re: nevermind

In addition to some things others have said:

1.) Install f.lux on your computer if you use one later in the day.
2.) Be sure you are getting outside in the bright sun during the day.
3.) Develop a SOLID bedtime routine.
a.) Turn off or avoid all screens 1:30 before bedtime. The blue light and stimulation will interfere with quality sleep, including serotonin release. You don't need your phone.
b.) Turn off or dim all lights
c.) Take a cool shower
d.) Be sure your home is no higher than 72 degrees.
e.) Put some light music with no words (instrumental) on.
f.) Read some light fiction
g.) Your bedroom needs to be as dark as possible.
h.) Consider a magnesium supplement like Natural Calm.

Also, consider eating carbs at night if you aren't currently. There is a good connection (embraced especially by carb-backloaders) to evening carbs and good sleep.
