So had a bad night last night with a really bad headache which I put down to not drinking enough. So today I goto work armed with a bottle of water and have just about managed to drink 1.5ltrs. I managed breakfast and lunch but now I just feel cold and shivery with a really bad headache and a sore throat. I feel sick like you do when you are hungry but couldn't manage to eat a thing right now. Am guessing I am going down with something but wondered if it could be just some weird pregnancy symptom?
