The lyrics above have errors and are missing two pairs of verses.
Here is exactly what is on the album:

ow I have always been a timid soul, afraid of having fun.
I let my golden chances slip away.
But now my ways have all been changed, a new life is begun,
and it happened in a most peculiar way.

This man came up to me one day and whispered in my ear
"I've got something you'll be awfully glad you tried.
It will free your inhibitions, it will banish all your fears.
We call it Dr. Jekyll's Cola 'cause you'll never have to hide!"

Chorus:
He said "Drink Dr. Jekyll's Cola and your world will open wide.
You will satisfy those urges that have always been denied,
You will liberate the swinger that was buried deep inside.
If you drink Dr. Jekyll's Cola then you'll never have to hide!"

Well, I handed over fifty bucks and I bought a case right there.
You know, he didn't even give me change.
He popped a bottle open, He said "Drink it if you dare!"
I did and started right in feeling strange!

My shoes changed into sandals, and my slacks to tie-dyed jeans.
My shirt and tie just vanished in the air.
Emblazoned on my t-shirt was a word I'd thought obscene,
And suddenly I noticed I was growing longer hair.

Chorus

Well, I made some money selling pot and leased a swingin' pad.
Invited over all the girls I knew.
I went and bought a Berkeley Barb and I answered every ad.
That kept me busy for a week or two.

I joined the Sexual Freedom League, but found them much too tame,
So I searched around for other games to play.
Then I moved into the "jet-set" and achieved some minor fame
By working out a method for seducing Doris Day.

Chorus: I said drink …..

Well, if you want my formula, the best way to begin
Is with the things the preachers have proscribed.
I bought a book the church put out to warn us against sin
And I practiced each perversion it described.

At first I thought I might run out of pleasures to embrace,
But endless was the list of things denied.
So I go to bed each morning with a smile upon my face.
I'm usually exhausted, but I'm always satisfied!

Chorus: If you drink ……

So if you look around and find a world that’s filled with pain
The answer might be something that we’ve lost.
Our fathers and our mothers duly taught us to abstain
And they left it up to us to pay the cost.

The secret of my magic brew is right here in this song
It’s nothing that you haven’t heard before
It’s just to wipe away the lie that loving can be wrong
Cause the folks that don’t make love are the ones that make the war.

Chorus: So let’s drink ….
