Oh good, paracetamol kills livers, they might be your best bet with benzos while you are awake because of breathing difficulties mixing the two but 30mgs isn't as bad as those ones in Canada with12mg codeine and paracetamol.
I read that withdraw is 7-10 days, at least it isn't methadone which takes weeks, try codeine and small amounts of benzos to try to counteract withdrawals but stop benzos if breathing problems arise. America's medical system is different but 7-10 days of benzos shouldn't be an issue if you try to use them moderately. Try codeine and benzos in moderation while wide awake to see reaction it might help. I get the impression that seeing a doctor can take a while in New

but America has different issues. Clonidine is a heart med used off label to help, my doctor gives them to me, non controlled
I can only say that if you can use codeine and benzos till withdraws pass, then taper codeine down you might be able to be done with opiates. Lucemyrais a drug used for withdrawals(lofexidine hydrochloride) not sure of availability in New Zealand, but if you can make it 7-10 days on codeine and benzos and try some gabapentin it can reduce sy.ptoms but all three are addictive but 7-10 days is not a hugh issue, try the temezipam(mis) also it is a longer lasting benzo and less likely to cause problems but Ativan will take some symptoms away. Hopefully the codeine will take care of some or more of opiate issues but take in moderation cause mixing the two is not that great, I did it with oxycodone. Morphine and Ativan but at therapeutic levels, not a problem.
You may have to taper codeine down, if they work you may be done with opiates.
