Can I drive a car or work after the hypnosis?

Yes you can.
Depending on the type of session you are immediately operational again. If necessary, have a little walk around, if you’re still feeling a bit to relaxed.
After Body Wisdom, Past Life Regression and other intense and longer sessions, I strongly recommend to plan your schedule accordingly, so that you can spare time for yourself after the session. You can go for a walk or just have a nice, peaceful rest. Experience has shown that you will need this time.
