im on day 6 of starting zoloft, and seems like my anxiety has been a little higher the past few days,and a headache everyday is that normal?

i think it is.and thats why they gave me the xanax to take to help with the side effects, i only took a .25 during the day the past 3 days,and the other half at night to sleep (been taking it at night for about 2 weeks now,but didnt take it during the day at all until 3 days ago) im praying its not a sign that the meds arent working.
