I think a big part of my memory problems is sleep deprivation. My mind is too active to let me sleep
Sounds like caffeine to me.
I used to be a caffeine junkie. Since I cut it out of my diet, I fall asleep in minutes after my head hits the pillow.
Try this little experiment...
For one whole week, do not drink or eat *ANY* caffeine.
This includes...
Coffee (even decaff. decaff still has some caffeine)
Tea (iced and hot. green, white, and black)
Chocolate (this one is my weakness)
Soda (not just colas. Watch out for Barq's root beer and sunkist orange in certain parts of the country, among others. Probably best to avoid all soda.)
"Herbal" supplements (they often contain guarana, kola nut, green tea extract, and other disguised forms of caffeine).
Challenge your family to quit with you for one week. You'll be surprised how hard it is.
