Medications side effects query.

My current treating doctor has made a change in Paxidep Cr 25 mg which I was taking at night along with Mirnite 15 mg and Etilaam pro 20. Now Paxidep has been prescribed to be taken in morning along with Etilaam Pro 20. Now I do have a good night sleep which I was struggling to get when Paxidep was taken at night. But Paxidep and Etilaam pro in the morning are causing some discomforts. I have been having light headedness feeling and kind of vertigo feeling especially after getting up from sitting on lying down position and mild headaches. I wanted to know whether these are some side effects of the medications because I can't seem to find these side effects listed in Google for the above medications. I am currently being treated for depression and anxiety disorder.
