I hope you're joking.. As far as time goes you can talk to your artist. My artist and I have sessions like therapy.. every artist is different, they may ask you not to talk or they could be like my artist. I usually read if I'm there for 6 hours or more. Other than that there really isn't much you can take (vitamin wise) to help with healing. Just LISTEN to your artist, they know best. Don't go off what anyone tells you. There is a reason they are still in business. Good luck and I hope you enjoy your experience, oh yeah, welcome to the addiction.
