I DONT!
You started the other thread stating you thought it was back and we chimed in with our opinions and ideas but you never responded.Now you start this thread stating you are basically giving up on your snake.
If the meds seemed to make the snake better but the RI is back or was never gone and actually just more advanced it most likely means your husbandry is off. Pit asked for a setup run down but got nothing. We cant help you if you don't allow it. Help us help you so you can help the snake.
I don't think you are going to find anybody telling you to give up now, you just need to get things right.
If you are not willing to do what it takes then rehome the snake to somebody that will bring it back to health.
