I would say this is a side effect. I take a different anti-depressant, and my stomach was upset for a few days. I hope that you are eating. If your not eating then the dizziness can come from that. Try drinking some orange juice, and some milk. The other side effect is what I call feeling like your high. I told my PDOC this, and she told me that it would go away, and it did. Another thing that helped me was taking the meds before I went to sleep. I know it is very hard right now, but you will feel better soon just hang in there.
