Yes, please see a doctor. At the very least, have someone you trust to watch you. Keep a list of the closest hospitals, urgent care or emergency rooms at hand. Call 911 if you need to.
Detox doesn't have to be horrific, with proper medical supervision it wasn't so bad for me. I was treated very well and with much kindness. I never felt I was being judged or poorly thought-of by the staff.
Take care of yourself.
Love,
Lenina
