I've been on pretty much most meds for mdd, some work for as much as up to a year then they poop out. Pristiq worked so well then nothing. I am currently on bupropion sr 200, doesn't do much but I keep taking it. Anyway my dr. is trying a combo of brintellix, bupropion, seroquel and trazadone. Any opinions on this combo and is it possible that pristiq after being off it a year could work again?
