As many of you know, I am in the depths of hell from a cold turkey benzo withdrawal. Talking to people and reading stories on various benzo survival forums, the effects of a withdrawal mimic adrenal Fatigue and Chronic-Fatigue-Syndrome almost to the tee. So benzo withdrawal, and tolerance withdrawal, due to the high state of stress it puts the body into, can cause AF.
I was also warranted to 'kindling' by my doctor, a process of trying many hypnotic drugs to make me sleep, and each drug causing neurological changes in its own withdrawal..so over two years and around 15 different drugs, you get the picture!
Glutamate has come up time and time again, and has been linked with why benzo withdrawal is so bad, and I read this today, makes interesting reading for those of you who are still in the brutal stress not sleeping zone of AF. Glutamate and Gaba go hand in hand, if gaba is reduced, glutamate is increased, which is the 'excitable' neuron enhancer, with gaba being the calming. Gaba is reduced by medication, lack of sleep, stress...its part of a picture where I am starting to believe not EVERYTHING is cortisol and adrenal related
