As I've paid more attention to what aggravates my symptoms, I've realized that I don't tolerate sitting at a desk for much more than 1/2 hour before I start feeling potsy - not like standing for 10 minutes, but still symptomatic. I suspect that on some days I'll find I can extend that time. Meanwhile I'd love to find something to allow me to sit up for long periods of time. As far as POTS, I do pretty well in a good recliner, but even the best supporting recliner weakens the low back. We are in the very slow process of getting my bead room / office functional. I'd love to be able to work in there. Worst case, I can alternate between the desk and my bed, but I really hate doing that. Any idea how long I need to lie down just to stop the POTS enough to sit for another half hour?
