I wake up with the morning sun and think about you
I flip the radio to 'on' and think about you
Your voice is going 'round my head, I only hear you
I'm acting like a lovesick girl with nothing to do

But dream about what you do to me
I'm inside out, going crazy

Holding on to reason but my grip is slippen
Barely hanging on
'Cause all I wanted is you

My mind is driving me insane
You keep on messing with my brain
Got me corrupted and confused
Under the influence of you
Just when I think I've had enough
You got me falling for your love again
What can I do?
I'm caught under the influence of you

My heart is starting to defend these thoughts about you
I'm almost tempted to confess but there's so much to lose
My independence, oh, what can I do? 
I wish I could pretend that it's not true

And no big thing, take it or leave it, yeah
You don't control my emotions

I'm hanging unto reason but my grip is slippen
I'm all strung up
'Cause all I wanted is you

My mind is driving me insane
You keep on messing with my brain
Got me corrupted and confused
Under the influence of you
Just when I think I've had enough
You got me falling for your love again
What can I do?
I'm caught under the influence of you

Night and day
Here I go again
It's hard to say
Baby, I need you
But who am I fooling?

My mind is driving me insane, yeah
You keep on messing with my brain, yeah

My mind is driving me insane
You keep on messing with my brain
Got me corrupted and confused
Under the influence of you
Just when I think I've had enough
You got me falling for your love again
What can I do?
I'm caught under the influence of you

Under the influence of you, yeah
Under the influence of you (under the influence of you)
