Hi, my name is Belinda and I live in the UK. I am the mother of a 21 yr old daughter who has had FMS for several years now. I have noticed that as the winter progresses her symptoms get worse and this causes depression, which in turn makes symptoms worse. I think I am right in saying that FMS sufferers have lower melatonin/seratonin levels. It would make sense in that case that winter light levels = problems. Has anyone done any research, do you know, into light therapy and the use of light box? Or has anyone taken melatonin to help FMS. I would love to hear from anyone in the US. Here in the UK we have the idea that your doctors are way ahead of their UK colleagues. Hugs to all, Belinda.
