A single idiom or phrase that means " I didn't feel sleepy anymore"

Question

Is there any idiom/phrase that convey this meaning: "someone or something caused me not to feel sleepy anymore at a specific moment or situation"?

Please read these scenarios:

1. Last night ​​I was sound asleep when the telephone rang. I coudn't sleep again after that and lay awake until morning.

2. Suppose you have an exam tomorrow, and you haven't finished reviewing your book yet. Now you feel so sleepy that you decide to rinse/wash your face with cold water in order to remove (?) that sleepy feeling.

3. While you are going to your work by bus, you feel so drowsy that take a short nap, but a loud cry breaks (?) your nap, and you don't feel drowsy any more!

I have found these idioms and phrases by googling:

• Somebody or something made me awake

• I was wide awake

• I washed the sleep out of my face

• I couldn't get back to sleep

Actually, I'm looking for a single idiom, or phrase that can be used in all those situations I illustrated in my examples.
