I feel drowsy but not tired what do I do
I'm tired but don't feel like sleeping
Lay down because you don't want to fall, avoid stairs, drink and eat something, try to relax :)
watch or do something
Drink warm milk works all the time!
Read a book
Watch a really dumb and boring show on your phone,iPad, or iPod and lay in your bed in sleeping clothes and watch it
get off any medication you on!
If you want to stay awake drink coffee or take a B complex supplement.
