How to transition between subs & oxy

[Asfartas49]

I've been on subs for months, but pulled my back out. Yesterday i stupidly took an oxy (20mg) at around 2pm (usually take subs at night). Shocker, didn't feel much. The next day however, felt like a minor withdrawal.
Today I took an oxy (40mg) and felt it a bit more, but now I'm wondering if I can take my sub without slipping into the horror of precipitated withdrawal.

Since the sub is still in my system (32 hour half life right?) can I still take my sub now, or will I get sick? Should I wait 24 hours after taking the damn oxy?

You should absolutely wait at least 24 hours. My rule for myself, so I never go in to precipitated withdrawl, is to wait until I KNOW FOR A FACT that I am starting withdrawl before I take my first dose of sub. And I usually double my maintenance dose for my first dose as well to avoid any issues.
