I have been taking morphine based drugs for 10 years due to chronic back issues, decided to stop taking as side effects got too much (effecting heart and gut), but still find I have a cough, which only come on after stopping medication (about 4 months after), it seems to come in bouts, might be gone a week then back... it's more like my throat closes and I struggle for air for a second, then cough and it clears... also have a horrible taste in mouth most of the time. Does anyone else have experience with this? How long does it last? Doctor is totally useless and is only interested in putting me back on the medication, which is not happening! Any advice or support would be greatly received! Thanks
