Songwriters: Morgan, Brian Alexander; Troutman, Roger; Murdock, Shirley; Troutman, Larry;I don't know what it is that you've done to me  But it's caused me to act in such a crazy way  Whatever it is that you do when you do what you're doing  It's a feeling that I don't understand    'Cause my heart starts beating triple time  With thoughts of loving you on my mind  I can't figure out just what to do  When the cause and cure is you    I get so weak in the knees, I can hardly speak  I lose all control and something takes over me  In a daze and it's so amazing  It's not a phase, I want you to stay with me    By my side, I swallow my pride  Your love is so sweet  It knocks me right off of my feet  Can't explain why your loving makes me weak    Time after time, after time I try to fight it  But your love is strong, it keeps on holding on  Resistance is down  When you're around, cries fading  In my condition, I don't want to be alone    'Cause my heart starts beating triple time  With thoughts of loving you on my mind  I can't figure out just what to do  When the cause and cure is you    I get so weak in the knees, I can hardly speak  I lose all control and something takes over me  In a daze and it's so amazing  It's not a phase, I want you to stay with me    By my side, I swallow my pride  Your love is so sweet  It knocks me right off of my feet  Can't explain why your loving makes me weak    I try hard to fight it  No way can I deny it  You're love's so sweet, knocks me off my feet    I get so weak in the knees, I can hardly speak  I lose all control and something takes over me  In a daze and it's so amazing  It's not a phase, I want you to stay with me    By my side, I swallow my pride  Your love is so sweet  It knocks me right off of my feet  Can't explain why your loving makes me weak    (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 'bout the way you do  The things you do-ooo-ooo, it  (Knocks me right off of my feet)  Ohh, off my feet  Can't explain why your lovin' makes me weak    I get so weak in the knees, I can hardly speak  I lose all control and something takes over me  In a daze and it's so amazing  It's not a phase, I want you to stay with me    By my side, I swallow my pride  Your love is so sweet  It knocks me right off of my feet  Can't explain why your loving makes me weak      © BAM JAMS MUSIC; MUSIC CORPORATION OF AMERICA;    these lyrics are last corrected by her
