A state of feeling dizzy and confused is grogginess. Once you get past the initial grogginess of waking up at three in the morning, you'll be excited to head out on your camping trip.
The noun grogginess comes from grog, an old-fashioned alcoholic drink favored by 18th-century sailors. Grogginess was originally a state of being under the influence of grog — tipsy, weak, or dazed. Starting around 1830, boxers started using it to describe the dizzy, shaky state caused by being punched in the head a few times. If you're feeling woozy for any reason, you're experiencing grogginess.
