Annaliese, dx hyper POTS. my symptoms were tremulousness, dizziness, fatigue, nausea, brain fog, BP spikes (highest to 177/121...my BP used to be always 100-110/60-70), flushing, rapid weight loss 103-->97# in 2 days at onset due to hypovolemia (my clothes fit the same). I am also on month 4 of dr Levine's protocol and a very high salt diet. With this, I feel nearly normal, but still have BP spikes just not as bad
