Many thanks for all your help, I'm impressed! The ones left are:
3. Turned up unconscious in wild!
5. Showing a bit of restraint, give up a pay award!
11. Coming back, find love on boat for couples?
13. Take some letters from them if I go back!
16. Stole unwanted third?
17. Representative inside bein' sick, we hear!
and a new one
18. Odds on fling?
Thanks again, any further help appreciated.
