Lyrics Pocari Sweat - Deaf Havana

I was on a bridge in Singapore, thinking of jumping
Then I looked up at the skyline
And it reminded me of London
Used to be my home, now it's a place I can't afford
To live in anymore and it's all my fault

You can't really be homesick when your whole life's a mess
Getting sick of my drinking? Well, I couldn't care less
Fell asleep on my plane and I dreamt that we fell to our deaths
And I woke up alone and upset

Lost count of the airports 'cause I drink to forget
Try to throw up for good luck, but I got nothing left
Jumped out of the car for a bottle of Pocari Sweat
Good God, this is as low as it gets

How the hell do I come back from this?
