I am 34 and was diagnosed with Fibromyalgia a couple of years ago, and I seem to have received better health care once diagnosed than many others. I was given two types of antidepressants to help me sleep once I finally got into a decent sleep pattern, i.e. bed at 9pm and up at 7.30 life seemed to improve. I also managed to reduce the number of sleeping tablets to about three a week, once the sleep pattern was established. I used to sleep during the day, when I came home from work, by having proper sleep at night I managed to stop the day sleep, it was a viscious circle, as if you sleep during the day you don't sleep as well at night, so I would recommend you get your night sleep sorted as it helps a lot.
With regard to pain, I was given a number of painkillers which I used to take regularly, approx 17 a day !, I was prescribed hydrotherapy which was excellent and this greatly improved my movement, and I have continued to try and do exercise which does help although it is painful initially, but it does improve over time.
I was made redundant in December and only take the painkillers occassionally now, but I have continued to remain active although recently had an unconnected ankle operation, which means the pain is starting to return, and my sleep pattern is not as good as it was, but at least I can manage it now, and find that when having good days to do as much as possible, and bad days to try and rest.
The physio I saw explained the disease to me as toxins in the body that attack the joints, and the lack of deep sleep means that "endorphins?" are not released to attack the toxins, but that the endorphins are released when exercising and therefore reduce the toxins. I do gentle exercise where possible and have found that this does help.
However, I do agree that people think you are making it up because you look well, but there is a letter on one of the websites can't remember which one, which explains how I felt, I printed this off and gave friends and family a copy and the response was much better.
