Clearly too many prescriptions and way too many combinations...
sounds like your husband takes things that contradict the other's effect...
dangerous combinations but you already know that...
now what are you going to do....not much for him but alot for yourself
sounds like there are no small children around (the plus side of being "older"...LOL)....that's a blessing....perhaps you can focus on yourself.....get out of the house and away from the drama...a movie, a friend, a walk
offer medical care but once its refused then let it be and take care of you
if he won't consider in patient then so be it...but don't let yourself become his home care....
there are facilities that can help him taper and withdraw (and many of his meds need tapering rather than quick withdrawal)
sudden withdrawal can definitely cause psychotic episodes...my RAS was hospitalized this winter due to a sudden change of meds (doctor controlled) that caused a psychotic episode
you are in my prayers...
please find some time to restore your sanity...away from his drama
perhaps go out with your son!
