Nauseous

I started 5mg and after 2 months went to 10mg. I was only on 10 mg for 2 weeks and had to go back to 5mg due to extreme anxiety and being very irritated and on edge. I am very sensitive to medications. I have now been back on 5mg for almost 2 weeks and for the last 2 days have had off and nausea. Could this be from the medication? I also have been experiencing off and on dizziness as well. I didn’t have these symptoms when I first started on the 5mg.
