Possibly allergies. FWIW I also tend to get a itchy throat when I'm overly tired.
Itchy throat might be a sign of candida infection, allergy, acid reflux or tonsillolith (stones in the tonsils). "runny nose sneezing coughing sore throat" are signs of post nasal drip due to sinusitis or acid reflux. Headache is a sign sinusitis.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
