Hi My Daughter Is 42 Years Old And Had Been

hi my daughter is 42 years old and had been on percocets for about 15 years and has chrones and ankclosing spondilitis, then she developed a very bad case of pacreatitis and was pregnant at the time . the doctors treated her with demerol because they felt it ws safer for the baby along with fentenol. she is now off the fentenol and does not take any percocets any more but she is on injectable demerol 100 mg every four hours was 120- she is trying very hard to cut it down to nothiing . we went to a doctor recomended by the addac people and he has recomended that she try suboxone and she has been given 2 pilles of that starting yesterday at 330 pm . we went on line and read about this drug and we are very scared of it. Both from what i have read are not good ! her injection sites are very lumpy and I am worried that the medication will not disperse and sit in there and then release when not suppsoed to. because we are scared of the suboxone she has not taken any more today nor taken any denerol. Please help us to decide what is the best way ..... she does not want to be on another narcotic to replace the one she is on and wants to quit this by decreasing the demerol slowly .... what are your thoughts ? the doctor of the suboxone is very vague about the length of time to be on it and we are scared
