Hi my name is amanda, and im 30. over the last two weeks ive been suffering with headaches. Ive recently began drinking coffee again after a year absence due to panic attacks. I only have one coffee a day, around 10.30 am (instant coffee) and my headaches start roughly an 45 minutes after and they last all day and night (forehead pain) i get blurred vision with the headaches too. Do you think its the cafeine thats causing the headaches?
