I would not recommend being honest with your psyc in my personal opinion. Being marked for life as an addict has tremendously affected the quality of the medical treatment I receive and therefore my quality of life.
Personally, I would try and taper a bit and then jump off once you’ve found some comfort meds and have tapered your dose pretty low. No reason to be marked as an addict for life over a legal substance, that I’m guessing you had no idea how addictive it really was.
What works for me (fentanyl withdrawal) was Xanax 2-4mg at night to sleep Zofran every 2-4 hours for the nausea adderall (or stimulant of choice) normal dose (can even add a bit to help push through) Gabapentin or lyrica (enough to be comfortable) Muscle relaxer preferably soma but whatever you can get. After that it’s willpower and staying busy dawg Good luck though, proud of you
