Yeah Soni its just a waiting game you will go to bed 1 night and wake in the morning and think to yourself i had no pain last night thats what happens, just gradually disappears. I used to have a lot of back pain if i lay on my back before the op but it was better for me having the cpap machine but, eventually after losing a fair amount of weight i sleep on my back and sides and dont have to use my cpap any more, I have never slept a full 8 hrs I have always been 1 for waking up through the night I try not to come down stairs now, try to stay in bed and go back to sleep. I f you have to have a nap through the day don't worry about it at this stage once you get back to work you won;t need it. I have found that i am going to bed later now on a night, I used to go to bed quite early and if i was going out on an evening sometimes had a n afternoon kip don't do that at all now. So things do will change for you just hang on in there xx
