... 15 mg at night I get serious pressure on both sides of my head that keeps me awake all night. Feels like my head is ready to explode ! Tried Tylenol to relieve the pressure and pain to no avail. Went to ER this morning and they suggest that I back off the 15 mg at night and go back to 7.50 until I can get a hold of my doctor tomorrow. No sleep in four days is starting to take its toll on me! Suggestions? Help!
