This is about as unwise as "Hey! I'm going to take massive amounts of heroin and xanax and then operate my car." A REALLY REALLY bad idea! A recipe for complete disaster.
BUT, it your body, your life and your choice. I would say be prepared. Bring music, a trip sitter (someone to assure you that things will be ok and do some "clean up" if needed) and other things that you find relaxing, enjoyable and calming. Xanax and a anti psychotic might be helpful.
If you choose to do this, please let us know how it goes.
I would say do to the likely problematic nature of this I would suggest carrying identification and contact numbers on your person.
