The mind can be a very powerful thing, but there is plenty you can do to distract it.
Try setting your mood, be in a setting you are comfortable in (ex. your favorite room) use some nice relaxing music, soft lighting, something good to eat, and a nice cold drink.

Being high is all about being comfortable for me. Everything around you has an effect on how you feel. Put your self in the most comfortable setting possible and you should be good to go! :thumbsup:
Relax and have fun.
