Most of the suggestions on here are for getting off to sleep whereas ACE has said he has no problems there. His problem is waking up halfway through the night, after 4 hours sleep. ACE, although the pain has gone, it may be that your body has got used to waking at that time, perhaps from the period when you had medication. Once you start doing a lot more, I am sure you will sleep right through the night. If you start taking anything in the early hour your body will get used to that too. Just hang in there and time will sort it out. Are you back at work yet?
If you can't face that what about a foot spa with the oils in it.
