Fentanyl patch+ oxy and tons of benzos

Would this work I heard fentanyl is not a painful death I was able to find someone to buy this from I read chewing on a fentanyl patch works fast

But to not get sick maybe i need to take an anti nausea medication before

I honestly dont know any other way where there is less suffering

I dont want to hear anyone telling me not to do it i need to know if its actually still painful or not

I already have a mild oxy/benzo addiction and i probably need more since i have tolerance

These thoughts been there for years and i dont think anything will change it
