What do you mean by "slightly modified"? TR really is your best option for now. From our experience here, getting to green as much as possible is the one way to keep those antibodies at bay. TR is your best chance of getting there.
That requires learning Oberon's patterns and cycles. One thing to note, since you didn't give R last night, and he was on his way up at +2, I would have taken the opportunity to put away the test kit until the AM. His onset seems to be around +2, if he's not on his way down then, you have the permission slip to sleep. I used to spend ages before I went to bed, trying to figure out if Neko would be safe if I didn't set an alarm to get up. By that I meant - no lower than very upper greens. Look at Oberon's cycles where he's gone green or low blues. At what point in that cycle could you have seen he was going lower? If you looked at that particular cycle plus a couple cycles before then, were there any other commonalities with other cycles where he went lower? Neko had a particular 3 cycle pattern that gave me a heads up she would be going lower.
Does Oberon generally show NDW (new dose wonkiness), seems to have that today. If so, when? If it's always a cycles 1-2 or 2-3, then you can relax the testing on those cycles. How long does he take to clear bounces? All these questions and more can help you figure out Oberon's general direction and whether he'll be safe when you want to go to sleep. You do an awesome job testing, but you really do need to save it for when he's in low blues and greens.
