I was an active 47-year-old mother of three teenagers, working as a university professor and playing regular competitive tennis when I fell ill with pneumonia in February 2013. This was when the dizziness and collapsing began, and although it was worrying, I thought the collapsing was part of having pneumonia and the dizziness was an infection of the inner ear called labyrinthitis. After four days in the hospital with oxygen and intravenous antibiotics, I was sent home to recover.

This took ages: I had four months off work; needed constant care; and was unable to do anything around the house. When I finally resumed short working days, all of my energy went into the day, and I needed to lie on the sofa all evening. However, at least the collapsing had stopped and the dizziness and balance problems had reduced.
On resuming a somewhat more active working life after the summer, the collapsing struck again, and began to happen as many as eight times a week. These episodes lasted about 30-60 minutes and involved intense dizziness and nausea, palpitations, shortness of breath, paralysis of my legs, a feeling of hardly being able to hold my head up, cold extremities, pallor, and a hot and sweaty body. Often, bad bouts of collapsing were associated with neck/back pain and soreness. I could barely speak and had to immediately ease myself to the floor with my arms when the collapses happened. Even on days when I was not collapsing, there were many occasions when I was unable to leave the house because I simply could not walk. I felt particularly terrible in the mornings (dizzy, weak, nauseous, short of breath, headache), but things would often ease later on. After an emergency hospital admission in late November, I was relieved when PoTS was suggested by a specialist, and I embarked on further tests.
By Christmas, however, I was hardly able to function. I felt that every ounce of life was draining out of me. My husband was carrying me around the house and my children were bathing me. Worryingly the collapses had taken on a more sinister note and included uncontrollable shaking and convulsions. At this point, very early in 2014, I saw an endocrinologist who witnessed a full collapse (in his waiting room), and after another emergency hospital admission, said he suspected hyperinsulinemia (which may exacerbate PoTS). He immediately put me on a very low carbohydrate diet. I was by now bedridden, weak and exhausted, but on following the diet, the collapsing largely stopped. Shortly afterward, a neurologist agreed that I had PoTS, or something very like it, and suggested graded exercise.
It is taking me a long time to recover, and I still have plenty of bad days with occasional collapses, but I am making progress. It is slow, emotionally painful, and often disheartening, but I want to share what I have done because it may help others. I am a scientist and cannot help measuring and recording things, and my doctors probably think I am obsessional, but it is my way of coping!
Here is my daily plan, which includes advice taken from the PoTS UK website, medical advice I have received, and a few ideas of my own:
