I really feel for your daughter and your entire family. This must be terrifying. I will give you my "opinion." i have RSD and take lots of meds, but also have many people in my life with substance abuse issues. Be honest with your daughter about your concern. Tell her how scared you were to see her take that much at once. Make sure that if she has multiple doctors writing her prescriptions, they all know what the other one is writing. 8 Percocet is definately alot!!!! When mixing all those meds together, you must take them exactly at the doctors recommended dosage or respiratory depression issues come into play & could be deadly. Whether she has addiction issues or not, this sounds like way too much meds. This is coming from someone who takes 10 or more different meds a day. I have seen alot of pain med abuse with my loved ones and it is hard to deal with, especially when you try to confront them & they try to justify it bY saying they have scripts for it all. It may be several different docs or just one script happy doc....alot of those out there. If she is needing to take 8 percocets, they must not be working for her. If they are not effective, they can try other pain meds that may work good enough that she can take her prescribed dosage. No doctor would purposefully dope her up that much. RSD is an extremely painful disease. Maybe a patch pain med would help her so she cant take more than directed. Im not saying she has an addiction. I dont know her. But it sounds like she is overmedicating, even if she is still in pain after taking that much. I take pain meds but had to learn to accept that i will always be in pain, even with all the meds. Maybe they can try some other meds and find something that works better. Feel free to PM me if you want to discuss this more in privafe in more detail. I would live to help because i have seen personally so many lives destroyed by pain meds. Its all about finding that happy medium. I wish you luck & hope you can get to the bottom of this. I know it will. E painful, but maybe her moving in temporarily will be a good thing so you can keep an eye on her until you know what you are dealing with. Make it clear that hou will not allow misuse of meds in your home & distribute each dosage to her if you must if gou suspect abuse. She will not be happy but at least you will know she is safe & getting the help with daily living that she needs from you. You could warn her that if she decides to abuse her rsd meds, the docs will take her off of them......then she will really be in pain. I always remind myself of that because i dont know what i'd do if i abused them and had them taken away completely. That theory may scare some reason into her. Please let me know if i can belp.
