I JUST started Lexapro this past Saturday and the first day or so, I didn't feel anything different. Yesterday and today, I've had a splitting headache and mild dizziness. I haven't done anything different (same amount of caffeine, same amount of sleep etc) I'm wondering in the long list of side effects, is this probably one of them and is it enough of a reason to contact my physician or just stick it out and give more time for my body to adjust?

Thanks in advance for your response.
