refining "what we're having"

The pre-chorus ended with the line "... with full zest" which is not only a rather uncommon expression but also a weak ending. Therefore, I put the line "I'll give it my best" at that outstanding position instead. That's much stronger! In consequence of this I now had to find a replacement for this particular line. I wrote "I won't rest", so the 'female' part of the pre-chorus now reads:

I could not stand it
if it ended
I won't rest
I'll give it my best

Gary, a friend from a songwriting discussion board, had observed that the second verse uses complete sentences like someone telling a story whereas the first verse uses incomplete ones. To modify the two lines in question I had to insert additional words (= syllables), which fortunately harmonize with the tune in my mind, nonetheless:

I was worn out and tired [I added "I was"]
after a hard working day
with no-one waiting
for me at home
I was out for a drink [I added "I was" here too, also using the phrase Gary suggested]
to fill the void
trying to block out
feeling alone

Now I should also get rid of the last line in the chorus: "... must be retained" which seems also too weak. I may have to scrap "can't be explained" as well, the line that rhymes with it.
