I read the words, and the first thought I had was, "I've known this person." Please note, this was not a comment on the lyrics. There's a reason for that. At some point, you have to know that you're the only one who knows what you're doing and you're better at it than the critics. I can understand asking about the obviously rough spots though. I can't find any. Closest thing is that "No panacea, snake oil or magic potion" has a spare syllable or the emphasis will be on 'oil', which is a bit strange. However, I can't think of anything better, and I suspect you'll fit it all in nicely in the singing.

Personally, I'd like a chorus or a bridge. Something to state the bl**ding obvious and tie the verses together. The song doesn't NEED this, though. Everyone (I'd guess) will remember someone in their lives that this song describes. Sometimes they write songs.
