Painkiller Addiction: IF you've been there personally, or have credible knowledge of same, can you answer this?

Similar thing happened to me a few years ago, was taking loads of painkillers due to back pain and benzos for anxiety and depression its so easy to get caught out by it.. anyway she may say shes not addicted but deep down she'll no she is. its funny wen ur given these pills by a doctor who agrees ur not well u get engulfed in ur pain and really begin to think u need the pills alot more often then u actually do! I got abnormal liver readings from routine blood tests my liver enzymes were supposed to be no more then 51ng/ml and they were 701ng/ml! it really gave me a wake up call wen i saw the damage i was doing it made me confront the issue at hand. I cut back on painkillers and benzos over the course of 3weeks and realised that without the painkillers i didnt actually have as much pain as i thought! apparently when the bodys in withdrawls it makes up pains so u feel the need to pop more! my advice to you is that instead of telling her shes adddicted (this never really helps cause wen addicted u truley beleive ur in pain and need these meds) get her to get some routine blood tests and wen she sees her liver enzymes broach the subject with her. I was only on half wat she is by ur description and only for 4months wen the damage began ive no doubt hers will show up hightened aswell
