Yes, my adrenal fatigue has improved in leaps and bounds. I'm still low on energy and get foggy when I'm tired but overall my health has really improved. I've actually even gone back to work (after about a year of being off)! So I truly believe in HV's general protocol.
Before the extreme insomnia, I too was waking up in the middle of the night with a pounding heart (actually almost went to the ER one night because I thought I might be having a heart attack). After going off all herbs (for good) and supplements (for about a week) my heart no longer wakes me up or disturbs me when falling asleep.
