Phenobarbital for rapid taper from relapse. Fucking scared of this med

So ive read all kinds of things.. mostly bad things. I have issues with my adrenals, apparently i shouldnt take it with adrenal problems, now thats serious. But it gets better.. its an immunosuppressant, exactly what i need as a severe chronic illness sufferer…. It causes trouble breathing in weakened patients (cool.. so i will have trouble breathing), it fucks up the thyroid (bc i dont have enough health problems), can cause a deadly rash, among like 3-4 other random sudden death conditions. And the worst of it - for some people it doesnt even work

I dunno.. do i really want this?

On memantine or antipsychoticsi had tardive dyskinesia, but now its starting to sound almost pleasant compared to a barb, am i paranoid?

Im trying to stop abd stabilize from a crazy 1-2 month binge on doses peaking at 2.5mg kpin, 20-60(?)mg ambien, 150mg lyrica

I was at 0.0625mg kpin, but 3 friends left me and one died and im an ambien addict
