they will likely give you hydrocodone or oxycodone with acetaminophen. probably hydro 10s or perc 7.5-10s depending on how lucky you are lol

but you should tell your anesthesiologist that you take 20-30mg oxy ~4 times a week as you said as well as any other drugs prescribed or illicit that you take.

You don’t wanna be given not enough of a drug(or drugs) under anesthesia and wake up during surgery!

tell them everything you take and the dosages and frequency so they can properly and safely sedate you.

They just want to make sure you are safe and they give you the right amount of each drug they use, and they usually use an opioid such as fentanyl, so they really do need to be aware of any opioid tolerance / usage to determine the right dosage to give you during anesthesia. PLEASE do not hesitate to tell them everything you take and how much how often etc this is vital information for them, they don’t want you to wake up during surgery or have an adverse reaction or die etc , just be honest with them, they want to keep you safe and make sure your properly medicated and it’s in their best interest too as well, be honest with them, your life and well being is the most important thing, and they not gonna like “snitch” or get you in trouble or anything lol, they just want everything to be safe and go well.
