[Verse 1]
Off my medication
Got me so unstable
Guess that I'm addicted to you
There's no way to save me
You know what I'm craving
Giving my addiction to you
You

[Pre-Chorus]
And if feels like
Nah nah nah nah nah
I can't get enough
I got you rushing through my veins
'Cause it feels like
Nah nah nah nah nah
I got you where you want
One more taste could drive me insane

[Chorus]
You know that I'm a headcase, baby
You know just how to make me crazy
Can't help that I'm a headcase, baby
I love the way your head tastes, baby

[Verse 2]
My biggest temptation
My favorite fixation
I'd stop everything just for you
Not more conversation
I just want you naked
I'd do anything just for you

[Pre-Chorus]
And if feels like
Nah nah nah nah nah
I can't get enough
I got you rushing through my veins
'Cause it feels like
Nah nah nah nah nah
I got you where you want
One more taste could drive me insane

[Chorus]
You know that I'm a head case, baby
You know just how to make me crazy
Can't help that I'm a headcase, baby
I love the way your head tastes, baby

[Post-Chorus]
'Cause I'm not thinking straight
No, I can't concentrate, yeah, baby
Yeah, baby
I'm not thinking straight
No, I can't concentrate, yeah, baby
Yeah, baby

[Bridge]
Nah nah nah nah nah
I can't get enough
I got you rushing through my veins
'Cause it feels like
Nah nah nah nah nah
I got you where you want
One more taste could drive me insane

[Chorus]
You know that I'm a headcase, baby
You know just how to make me crazy
Can't help that I'm a headcase, baby
I love the way your head tastes, baby

[Post-Chorus]
'Cause I'm not thinking straight
No, I can't concentrate, yeah, baby
Yeah, baby
I'm not thinking straight
No, I can't concentrate, yeah, baby
Yeah, baby
