I have had a few wierd symptoms lately. I have just put it down to exhaustion and withdrawall symptoms from nicotine (quit 2 months ago) However, I have noticed that when I wake up in the mornings my eyes are bloodshot some of the time. I often get headaches in the mastoid region behind the ear and just above the eyes. Lately, I have also been feeling more tired than usual. Some other symptoms include sweating and urine that is quite dark. Any ideas of what this could be???
