I'm curious when you will go in and change pump settings like I:C ratio and CR and basal rates (aside from temporary basal rates). Do you wait a few hours, a day, a few days? I feel like a big part of my problem with my control is that it's sooo variable from day to day and I think maybe I am either changing settings too often or not chancing them enough, I don't know. But, for example, I will have a day like yesterday:
5:55am - 6.7  - Breakfast
9:04am - 3.8  - Glucose tablets
9:51am - 5.1 
11:41am - 4.8  - Snack (no bolus) & exercise
12:39pm - 3.0  - Lunch
2:22pm - 8.9 
3:36pm - 8.1  - Correction
5:20pm - 2.9  - Glucose tablets & dinner
7:30pm - 3.6  - Tons of glucose tablets - felt MUCH lower than the number suggests, mouth went completely numb!
9:30pm - 6.0 
Followed immediately by a day like today:
5:54am - 9.4  - Correction
7:17am - 6.8 
8:34am - 4.8  - Breakfast
12:13pm - 12.5  - Correction
2:33pm - 13.4  - Correction (via shot) & +20% temp basal
4:03pm - 11.9  - Site change & correction
5:42pm - 9.9  - Correction
6:25pm - 9.3  - Dinner & correction
7:52pm - 10.5  - Exercise
9:01pm - 6.9 
10:01pm - 6.4 
Updated to add today:6:23am - 3.3  - Glucose tablets
8:09am - 5.4  - Breakfast
10:12am - 5.5  - Snack
12:10pm - 4.2  - Lunch
This is with literally the SAME settings as yesterday, and same breakfast (measured exactly). The only difference is that I was in a conference call all morning (and secretary, so taking minutes) and so couldn't exercise at 11:30 like I have been doing (not intense exercise, just 30 minutes walking).
But this is what drives me crazy - one day I'm going low constantly and the very next day I'm high constantly. Do I put my I:C and correction factor up? Or did I go low sometime in the morning and this is a rebound? Or do I just use a temporary rate and shots and correct all day and see what tomorrow is like before deciding whether to change settings? Knowing my body, tomorrow will be completely different!
Today I only ate chicken for lunch - I'm trying to not eat many carbs when high like people suggest - but my problem with that is my protein sources are extremely limited and with the way things go sometimes means I would end up not eating all day! This type of thing happens to me sooooo regularly (with either direction, high or low), probably every few days at least, or else I have days that are a mixture of bouncing from high to low and back again, and it drives me crazy!
I've been Type 1 for almost 23 years and am on a pump and try to keep meals to 25-35 carbs (or less if it works out - I can't eat nuts/peanuts, soy, eggs, or cheese so meat is my only real source of protein). And after all that time I still feel like I don't have a clue sometimes!
