Oh I am so sorry. I had the terrible Lupron headaches too. I tried the Tylenol but it didn't work so I ended up asking for something stronger. See if your RE can give you a couple of Vicodin to make it through. Also try lying down in a cool, dark room with no sound. I have used both hot(VERY hot) and cool compresses and both seem to help a little. Have DH give you a neck, shoulder, head massage.
When you are laying down concentrate on relaxing each muscle group/especially those in your neck and jaw. Just start from your toes and relax, go all the way to the top of your head and relax.
Hopefully something will help you through this. It sounds like a migraine to me!
