In reply to Queen of the Traverse:
I don't seem to be able to pm you? I think your settings don't accept it.
Agreed about the walks, I have continued short walks most days if possible.
Abdominal compression, I use a post surgery/pregnancy velcro binder, lots available online. I use it when sitting or standing (not lying down as it gives headaches, and not during or immediately after meals as it gives indigestion!).
Meds, really sorry you can't tolerate them. You probably know this or tried it but some people have success building them up from a very very low dose over a long period, like cutting the pills into quarters etc. Also if you don't tolerate them due to allergic reactions you've probably looked into mast cell activation? That's somewhat controllable with antihistamines I believe. And finally there are some natural alternatives to some of the meds: liquorice for fludrocortisone, huperzine a for pyridostigmine, butchers broom for midodrine. I've not tried any of those. I did read a case report of a woman who had undiagnosed orthostatic hypotension and had instinctively added huge quantities of liquorice tea and soy sauce to her diet, controlling things for many years!
Apnea, I had a study done privately, but I think if you had morning headaches, nighttime urination, daytime sleepiness or other sleep apnea symptoms your GP should arrange a test for you. I was able to enter the local NHS sleep service off the back of my private study, think that might be somewhat dependent on how your local GP and sleep clinic operates.
