My eyes are dry every morning an i have a headache.what can i do before bed to prevent waking up with it again?

See your doctor: Make sure you identify the cause of your headache, high blood pressure, migraine, etc. See your doctor to find out the cause.

Use Atificial Tears: You can use over the counter artificial tears. Depending on the dryness you can use an artifical tear drop or ointment at bedtime. In the morning use the drops. If this helps but not completely you should visit an eye specialist for additional evaluation and trearment.
