Hopefully you won't have any side effects. 🙂 The dizziness was intermittent. Sometimes happened when I was driving-ugh, and in my classroom, a few times on a walk, but it would pass. My doctor said to drink lots of water and take deep breaths in and out. It helped. I was so happy when it passed. One time I got so dizzy in my classroom that I felt like I was going to faint. My principal and the school nurse came and she had me lay down on the floor and put my feet/ up on a chair and take deep breaths. I sat up and drank some water and it all passed. Not great in front of my students, but luckily never happened again. I'll take the dizziness over gasping for air any day though! 🙂
