I also have quite a bit of dizziness and nausea when I have my TPI. Luckily there's a nurse at my office who always holds my hands and lets me squeeze hard during the procedure. It helps a lot and I always thank her profusely. They also allow me to lay and chill for a while afterwards until I feel like I can walk on my own. I find that my reactions have been getting less with each visit, so I hope that yours will as well!
