Not sure where to turn, 7 years experience of middle of night wakefulness . had a saliva test for hormones and adrenals, both out of whack, but which came first? Have tried many herbal solutions and even one pharmaceutical, but nothing holds, always end up after 6 months or so, back to sleeplessness . Now experiencing periods of what feels like fast pulse, have to take deep breaths, try to calm nervous system . Daily yoga practitioner and healthy eater, very little caffeine, can t take it. what is up?
