I’m sorry, but you appear to be a victim of relentless polypharmacy, taking tablets to counteract the side effects of other tablets. And taking both of an either/or choice. How did you get in this situation? It’s doubtful it was a hospital clinic.
Whatever else is going on, someone with some sense needs to take a look at your medication and jettison at least a third. Then at least you’ll be able to feel more normal.
This is just a personal opinion, but any doctor who prescribes oxycodone for regular medication should be taken out and shot. It’s killed thousands in the US, and is “black boxed” by the FDA, who control meds in the US.
The one thing you mustn’t do is drink any alcohol, and don’t stop taking any tablets without medical advice.
