Cure for insomina

Seriously my life is a little challenging right now. My hubby has a groin strain and is in quite a lot of pain. He can't have time off cos he does not get paid so he can't rest. He did manage 4 days but he is crap at sitting still. The pain is bad during the day but tolerable but at night he is in quite a bit of pain. Despite regular paracetamol and codeine he is still in pain. Consequently he is not sleeping very well. He does not sleep brilliantly at the best of times but the last two weeks have been particularly bad. He has actually got up on a couple of occasions at 2 am and 4 am to make the sandwiches for lunches the next day. Now me, courtesy of the prozac, can sleep for England and frequently do those of you who know me know how important my "nana" naps are to me ;-)
But what can I do, I have tried the whole bedtime routine thing, warm milky drink, relaxing etc. did not work, my neighbour has some Zopiclone and Tony had one last night (I know what you are all thinking don't shoot me we are desperate. anyway it did not even touch him!!!) I am thinking Nytol but if Zopiclone did not work will a herbal tablet which is not even monitored by the pharmaceutical industry so could be pressed talc for all I know.
I am at a loss I would love to hear your suggestions no matter how wierd and wacky cos we are quite desperate. I want to sleep without feeling guilty and Tony just wants to sleep. If someone suggests something and it works I may just send them a little gift to say massive thank you!!!
Sleep deprivation is the pits!
