That's good - it's a self treated condition, we need to make our own judgment calls, and it sounds like you're starting to get the confidence to experiment with it.
That's good too. You're observing things, thinking about why they happened, and hopefully thinking about how you, as the person in charge of your shots, might adjust it. (A persistent rise like that after the last bolus has worn out suggests basal needs to be higher)
Some of your posts in the past have been very negative, but there's been a subtle shift recently - instead of saying, "I can't do this", you're starting to move towards, "How can I do this?"
That's a big step, carry on.
PS: you've mentioned in other posts getting libre funded. Pursue that. Stick a blucon on top, run it to xdrip+. It's a massive safety blanket knowing your phone will ring if you're going too high or low. You might actually get a full nights sleep instead of early a.m. testing.
