Hi wakeover - it's helpful to include the numbers of letters & any you've placed, so that people without the puzzle can also help you - thanks! :-)

[Lie-in King]

Apologies, you have stated the numbers of letters - I need another drink, methinks! :-))

[wakeover]

Thanks Sandy Roe and L-I-K. I know LIK exactly what you mean and I did it and wrote it all out and then realised it was in the wrong box and it's so hot here and Man U are about to play.................................need I go on lol
