I'm not that well known with this, however, how you covered the basics, tell the doctor? tell other family members? does she have the support there? is she aware of her problem and wants to stop? it also seems she has some other issues as well. get a counseler, or phycologist someone she can talk to and get professional help. I hope this helps and I'm sure more people that maybe fermilliar with these situations will chime in. God bless
if she has a history of seizures with detox, perhaps you should speak with a doctor about switching to a long acting barbiturate like phenobarbital to withdrawal. i would try to find a detox center that has experience with barbiturates...this might be very hard to find these days. often a person is tapered on butalbital, but in this case it might actually be safer to use a longer acting barbiturate.
i don't think any single doctor can be an expert in all the things she needs...a primary care physician should be 'directing' all this though. i would also recommend discussing with the doctor slowly switching from fiorinal with codeine to fiorinal without codeine......say for example she's taking 10 per day, well one day replace one with fiorinal plain and the next day replace 2 doses with the plain and so on. usually codeine doesn't need a taper, but i think it might be better if she has a history of seizures.
