I went thru that too and nothing helped. I have a history of migraine problems so im used to taking stuff much stronger than tylenol. Id just lay in my bed and try to sleep it off til I had to go to work. Luckily its something that just faded away around 17-18wks. My dr told me they should fade away hopefully by 20wks. Hope you can find some relief soon!
Try caffeine with the Tylenol.
