yeah seems to be the case. It's odd. The opposite seems to be true for me. When I go through really bad POTS phases I find the only thing that helps is intense rest. I'm generally completely bed bound with the severity of the POTS symptoms. During those phases, which can last 6 months, if I try and do anything, my POTS gets worse for weeks and I get very violently ill to the point of not being able to eat at all. Yet after complete solid intense rest for months the symptoms do eventually abate and I become semi functional again,.ie able to shower, get around the house and outside occasionally. This happens over a course of maybe 2 or three weeks once it seems to click into getting better. I never know when the rug will be pulled from under me again though and when I'll spiral into disaster. Longest good phase I've had in a row was 6 months.
