Verse 1:
Am                                       Bb 
I don't know what it is that you've done to me
Am                                        Bbmaj7
but it's caused me to act in such a crazy way
Am                                                 Bb 
Whatever it is that you do when you do what you're doing
Am                          Bbmaj7
it's a feeling I don't understand
 
Bridge:
Cm7                            Eb  
Cause my heart starts beating triple time,
     Bbmaj7                 Bbm   
with thoughts of loving you on my mind
Cm7                     Eb  
I can't figure out just what to do,
         Bbmaj7    Am      C
when the cause and cure is you
 
Chorus:
         Am                      Dm7
I get so weak in the knees I can hardly speak
  Gm                   C               C   
I lose all control and something takes over me
Am                 Dm7         Gm
In a daze and it's so amazing, it's not a phase
  C           C         Am
I want you to stay with me, by my side
      Dm7                Gm
I swallow my pride, your love is so sweet
   C               A7        Dm7   G7
It knocks me right off of my feet
  Bbmaj7 Am               Gm     C        Bb  F
I can't  explain why your loving makes me weak
 
Verse 2:
     Am                                       Bb 
It's Time after time after time I've tried to fight it
    Am                                      Bbmaj7
But your love is strong it keeps on holding on
  Am                                          Bb 
Resistance is down when you're around, starts fading
   Am                               Bbmaj7
In my condition I don't want to be alone

I get so weak..
Blood starts racing through my veins
I get so weak..
Boy it's something I can't explain
I get so weak..
Something about the way you do
the things you do, it knocks me right off of my feet,
off of my feet
Can't explain why your loving makes me weak
