Last Wed my medications were increased

Thank you Jesus!!

from: 40 mg of oxycontin to 60 mg of oxycontin per day. Here is my new dosing schedule:
2:00 am. 20 mg.
8:00 am. 10 mg.
2:00 pm. 20 mg.
8:00 pm. 10 mg.
FYI - my doc is pretty flexible and I can take my meds however I really want. My meds come in 10 mg. tablets.
How long will it be before one should know before this stabilizes and one knows if this is an effective dosage?
Prior to this adjustment, I would wake up dry heaving and vomiting due to pain of a 9/10 every morning. I was taking my meds at 4 am and thought maybe if I moved it back to 2:00 my meds would surely be in by the time I woke up and I would not be as sleepy. Now I wake up with slight case of a nausea and pain levels of 6/7 and am not as sleepy which is great since I need to begin homeschooling the munchkins in the morning.
Most mornings I am requiring a BT within 1 hour of waking up.

This disturbs me that I still am needing a BT. One would think pain would be lower after a sleep and increased in meds but for me it is one of the worst times of day. Any suggestions/ideas?
Will taking 20 mg, 10 mg, 20 mg, and 10 mg. cause my bpl to ping pong since it is not one steady dose i.e. 20 mg, 20 mg, 20 mg, and 20 mg. ? Would I be better to go to taking 10 mg. every 4 hours?
Thank you for your help.
