What Causes Chronic Vomiting And Difficulty In Swallowing While On Lexapro?

Good morning. I definitely have a question to ask, but I am not entirely certain how to phrase it. Recently (2.5 weeks ago), I was prescribed Lexapro, 10mg per pose, per day. The first day or two, I felt fine, but the nausea and dizziness I was forewarned about, while taking the medication, hit me, but I am vomiting at least 2 times a day now and having moderate difficulty swallowing. The back of my throat feels extremely numb. I was told these feelings would pass, but they haven t, so I reduced my Lexapro dose down to 5mg a day. Should I try to take it every other day until my body adjusts? Or should I ask my PCP to perscribe an antinausea medication until the symptoms subside? There is family history of gastrointestinal issues and acid reflux. I have hypochloridia and minor glucose issues. I am struggling to adjust my food diet to try to subside the nausea, but I am not certain what I should be doing. Should I maybe go see a dietician again instead?
