Anecdotes of long-lasting worsening
u/TheAnimal777:
After that 10th day I never went again, but every night since I’ve been waking up at 3 or 4 am with massive adrenaline dumps. It basically feels like my fight or flight is on overdrive and I’ll wake up feeling like adrenaline, fear, and stress is pumping through my body, especially heart (sort of like hyper-adrenal dysautonomia). I’m usually unable to fall back asleep and it’s been pretty awful.

Agy_lena (ME/CFS):
HBOT for example. That made me permanently worse.
