We all know how important sleep is to this illness in order to feel slightly normal, since making some leaps and bounds with sleep using various supplements and diet, I can now sleep through from 12-8am however my fitbit tells me I am waking up regularly. What I have started to realise is that the slightest change in conditions can aggravate my nervous system and cause a big flare. Our house can get quite cold sometimes and I can go to bed a bit chilly but under a thick duvet and a hot water bottle. Of course at some point in the night I wake up feeling hot and that change seems to be an issue. Upon waking I have floaters in my eyes, a dry mouth, dark urine, I'm dizzy, uncoordinated (like MS feeling) and sometimes it flares my Fibro (That I don't really have any more generally). It then takes gallons of water and hours of resting to recover. This is something that would never affect me when healthy and if anything would be quite nice to be under a toasty duvet, nothing extremely hot about the temperature. What could this be? That ME is cellular dehydration and it pushes my cells over the edge? That the ANS/CNS is so sensitive that it flares everything up?
