I don't wear glasses regularly, but have reading glasses - I am longsighted.
Currently I take aspirin when it gets really bad, but I rather suffer through pain and find out what is wrong rather than suppressing it with pain killers.
Nausea is rare.
I forgot to mention that I am also concerned about my ability to memorise. Maybe some of these symptoms are age related. However, I am concerned that there are so many symptons and that they don't seem to go away although I actively try to lead a healthier life style.
