For first 2-3 months I was very anxious before each session. I didn't throw up nor have any other physical reaction as I learned how to relax my body whenever needed but I was pretty terrified. Then, it went better and I calmed downed, but a week ago I started the real trauma work so it is worse again (but not as bad as it was at the beginning). Thus, in my case it is more like a sinusoid curve...
