Well methadone+oxy+heroin withdrawal at the same time wasn't very pleasant.
Benzos are also really, really bad when you've abused a long acting one for a long time.
A short acting benzo abused at a high dose for a long time (alprazolam or brotizolam for example), is rather brutal as well. The acute withdrawal is rly bad with short acting benzos. But the PAWS from benzos are probably the worst of it.
The one time I got through my PAWS, was when I was clean for a year from everything (and in rehab all the while...).
My social anxiety was always too severe and too much of a social impairment though. So eventually I always went back to using benzos..
Thankfully though, ever since that time during which I was off benzos for a whole year, I have gotten it (benzos, not talking about opioids
) under control. I just don't get any recreational effects from benzos anymore. And I used to eat like what you could expect a whole month's supply worth of benzos every day when I was at my worst.
So I'm glad I managed to get a grip on my benzo use,
especially because it's a rather crucial medication for me to temper my severe anxiety on a daily basis.
