For those of you battling with POTS and orthostatic intolerance does anyone else find this is a million times worse when waking up and trying to get up for the first time? I am having real issues with this at the moment. By the middle of the day when I have finally got going I am ok, but first thing in the day for about 3 hours it's awful. Not only do I feel like a zombie, some days I am dizzy with vertigo (actual room can spin) often I am sweating as well and my pulse shoots up when I stand. Does anyone else find a difference in the times of the day for this and are mornings always the worst? Any ideas how to help this?
