Everyone is different, and the Trimix ingredient mix is not standard, so stepping even from .10 to .15 based on someone else's numbers is not at all wise. Talk to your Uro about
changes.
I went from a .10 (45 minutes) to .13, which generated a near-trip to the ER. I was out the door at 4 hours before it finally eased off. I find that experimenting can be dangerous. Back to .10, and I'm "sticking with it".
And all this at 6 weeks post op? I was still in depends pants and sitting on a plastic liner. You are doing better than great.
