Did it work for you? How did you feel after? Did you need to go more often?

I went one month ago , I had 4 sessions each of 15 minutes, I heard the guy is very good at it (I known personally people getting better for all sorts of problems , like getting full of energy and physical problems disappearing), but I still have the symptoms : lightheadedness, dizziness, brain fog, mild headaches, light sensitivity, sometimes nausea, fatigue, I get dizzier when I stand up too quickly (from the chair or bed). :(
