I think you need to be honest with your Pdoc .. The fact that you started too, well that takes it up a very big step.
If it were me? I would certainly go IP without a second thought.
While IP..... medications can be fiddled with much faster and you will be safe. Especially when Mixed, Pdocs can just slam you hard with meds for a couple days to just stop that horrid mess in it's tracks.
Being Mixed is pure hell on earth.
Stay safe
