Mental Health Major Confusion

[NYtonowhere]

My SO was on Opana 40mg a day til 6 days ago, he does have any withdrawal symptoms anymore. He is having continuing confusion that won't go away. Some symptoms he is feeling are:
long pauses during speech

• lack of awareness of location or time
• forgetting what a task is while it is being performed
• sudden changes in emotion, such as sudden agitation

He doesn't understand numbers, time, what things are. He was having anxiety because of it, but now is calm since he is getting used to it.

Has anyone experienced this? How long did it take to go away? Did you take any medications to help?

Thanks!

did he stop any other meds? does he have underlying psychiatric disorders?
