I’ve had this condition for 15 years, only diagnosed about 2 years ago after Tilt table test. Symptoms are much worse in the morning, with blood pressure in the 60 over 40 range. Also have supine hypertension so it’s hard to treat the low for raising the high. Wish I knew some magic answers. Also have diarrhea 3 -4 times in the morning after breakfast. I just signed up for this discussion group so hope there are others who can talk about the conditions affect on them.
