I have had a severe headache for the past five days. I go to sleep with it and wake up with it. I tried taking Tylenol but it hasn't helped. I have been drinking the recommended amount of water, sometimes more, and taking my vitamins. I have been getting enough sleep (like 10 hours). Does anyone have a suggestion as to how to alleviate this? I don't know what to do, but it is SO painful!!! Ugh!!!
