Hello, My husband has been suffering with headaches for several years now.. he has become addicted to hydrocodone.. he probably takes 12-15 per day and can't function without them.. he has just returned from a inpatient rehab after 4days he did really good while in they gave him a couple of different meds that took to edge off.. he knows in order to stay off of them he just can't take them anymore... but his headaches still persist.. can anyone give me any advise to help him..please reply..
