Withdrawals

Has anyone taken kratom to stop withdrawals from not taking oxycodone? My pain management doctor abandoned me ( and others) and didn't call in my refills. Now I am scared and going to have to deal with withdraws and I have no idea how I’m going to do that. Not only from oxycodone but from Xanax as well all at the same time I know that you can’t stop Xanax cold turkey. I went to the ER for help, but after waiting seven hours the charge nurse told me that there’s no way that a doctor would help me there and handed me a list of doctors to call. None of the doctors are taking new patients and I can’t be seeing at the earliest until the end of February. so I was wondering about Kratom .
