It's a theory. Hormones control most of our body ........ most of the time we aren't aware of the role they each play but boy, are we aware when they get out of kilter!
Cortisol: the waking up hormone: floored me in the 1990s. I would wake terrified

.
Adrenaline : causes anxiety, even though I know it's fight/flight response it's the physicality that makes me feel so ill
Propbiotics ect. : is that predictive text again

: R unlikely to influence the hormones at all. I have drunk
Actimel 4 years due to slow bowel transit

and I have had no effects on any other part of my body. Works the bowel nice and gently though ;-)
The gut is known as the 2nd brain though ........ which is where I feel ill, as soon as anxiety strikes or if I'm sitting an exam., visiting friends, going shopping .......... bugga ..........
For years I had restless legs. Bananas cured them

. I was eating more to stop that awful sudden hunger feeling and the side effect, after 5 nights, no restless legs. 4 me it's lack of potassium. Apparently.
If ever my gut is inflammed I am aware of a kind of burning and 'off' feeling

. I also have reflux which can get worse into full heartburn, sleeping becomes impossible until I have chewed at least two
Rennies 
.
Let us know?
