You are champions, those with Type 1. I need some advice. (Sorry this is long....)

For the past three days:
Thursday
7a 258 correction
12a 90 Unfortunately, it was a burger big bite from 7-11, only ate 1/2 the bread, but it was an unknown food substance, so a guess....
130p 279 correction
230p 284 continues to rise, so correct again (I know, BOB, but I also know that when my glucose is above 200, it takes a LOT more insulin to bring it down)
5 p 197 small correction
6 p 156 dinner, left BOB to do its job
9 p 118 finally a good number

Friday and Saturday were a mirror image of Thursday.

Now today:
7am 134 correction + food with a small breakfast (13 carbs)
11a 167 correction + food (something I eat all the time and know how to bolus for)
12p 297 correction
2 p 227 correction
3p 187, new site, new bottle of insulin, additional correction.

I did have a hard low on Wednesday night, so I can chalk Thursday up to its aftermath. But no lows, obviously, since then. I have changed sites twice, changed to a new bottle of insulin (just recently) and am running out of ideas. Even tried a brand new site, never used before, which is hard after 10 years of pumping! What worries me is that this is becoming a very unhealthy trend, one I am not used to (average glucose is 80 to 110)

Now, this was a road trip with the grandchildren and their parents. We ate in the condo every night, so there were not secret restaurant carbs to accuse. Great cool mountain weather, not sick, no idea what is making this happen. Oh, no ketones.

So the Question for my Champions is HUH?!?!?! Ideas? Just looked at the CGM numbers and glucose had fall en to 175, but has risen to 175 in 30 minutes.
