It takes awhile, hang in there. Regardless of meds or not it isn't abnormal to have occasional down times, they pass.
If they are getting worse or last longer than 2 weeks, I'd be concerned. Things take time, it is important that you start with small doses and titrate up, till the therapeutic dose is established for you.

Take care now and lots of luck,
