Both were followed with an extreme sore throat, joined the next day by something like a sinus and upper respiratory infection, and then flu-like symptoms
. Feels like a bad cold for a week after. I have not been formally allergy
tested but am fairly certain it is either a worsening allergy or perhaps something different is being added to sugar nowadays that some of us are more sensitive to.
I do not, however, feel tired when avoiding sugar, as you have mentioned.
