if shes taking it just for the hell of it or bc she says it makes her feel good or normal then she needs to go to rehab. she could O.D mixing all those things and taking all that crap for years is horrible for you. she obviously has a problem. if you want her to live you will make her go to rehab and stay there. I've seen my friends do this crap and they go to rehab but never end up staying. make her go and finish. thats not healthy
Are these medications prescribed to her by her doctor or she just took them because she thought she may have a need for it? The good news is that these 4 medications do not have an adverse reaction with each other, so it is safe to take them together, although not at the same time of course. The bad news is that since she has been taking them for several years, she may now have a problem getting off it since she has formed an addiction to it. The best thing for you to do is to bring her to a doctor or a rehab facility who will prescribe for her a program so that she can get rid of all those meds and detoxify her body as well. Hope she gets better.
