I was so out of touch with myself I didn't know what was causing what reactions.It was not untill a visit to the nutritional therapist,she helped me discover what was what.
In retrospect I have had these sensitivities/allergies since my teenage years.

And now I can spot it a mile off in other people,for example my family who sneeze &cough after taking a shower with their usual lethal cocktail of shampoos deodrants...etc
It is an everday occurance they do not even seem aware.
People think this is a normal reaction but it's usually not untill it stops people in their tracks with more prominent symptoms that the majority of people will keep soldiering on.
