I keep cutting back then going back onto my original dose, because I start feeling weird with less/or without it. I used to be on 16mg too but I'm only on 4mg now, down from 8mg, because I'm also on the abilify maintena injection and the 200mg thorazine. I don't want to be on 3 APs. Tonight will be the first night I don't take it at all, I'll definitely let you know if I have any side effects. I've been down to 4mg the past few days, I haven't had too many major withdrawal effects. I originally stopped 8mg cold turkey and the withdrawal effects were really bad, having psychotic symptoms, bad anxiety, panic attacks. But now that I'm doing it a little bit slower by tapering down it seems to be going a bit better.

I would just recommend going down slowly with your doctors guidance, as slow as you need. I don't know if perphenazine comes in 2 mg tablets but if it does maybe you could ask about going down to 14mg and so on, over a long period of time so the withdrawal is easier
