Is it safe to take Tylenol extra strength while pregnant? I read that it was fine. But I still want to research as much as possible. If it IS safe, should I stick to one capsule? Or would two be fine? The box says that adults should take two every few hours, but I don't know if that's "pushing it" for us pregnant women who are taking it.

Lastly, does it make you sleepy or drowsy at all? Thanks guys.
