Teresa, thanks for yours email. I’m sorry to hear about your health problems. Have you seen a doctor about these headache?mi really think you should go to your familiy doctor and tell her about them. You shouldn’t understimate the problem. Have you got any ither symptoms? You shouldn’t take too many aspirins. Try these remedies: you should drink a least a litre of water every day, and you shouldn’t eat chocolate for  a few days. Also, you ought to ask for an allergy test, as this might be the cause. You should sleep for a least seven hours every night, perhaps you’re tired. And I know you’re studying a lot at the moment, but you ought to take a rest sometimes. You should go for a walk or do some exercise outside in the fresh air. Let me know how you’re feeling soon!
