| I think you need to do some basal tests to really know what you need to do. Doing the tests sucks, really, but what you learn from it is great. I would also add, though, that I'm not convinced that the tests are always 100% accurate when you're on mdi, as opposed to the pump. According to the guidelines the results of my tests say I'm taking too much basal, but I've found a system that's working for me and giving me the results I want.
I don't know what you're carb ratio's are, but what you're saying makes me think that perhaps you need to increase you're basal and decrease your carb ratios.
A few months ago they had me on a small amount of basal and a larger amount of bolus and I found it to be a major roller coaster....way too easy to go low after meals.
I've raised my basal to as high as I can stand it and lowered my carb ratio's as I've gone along. Over the last few weeks I'm at about 65% basal and 35%bolus....I've found that with the basal being the major player I've got more steady b/s....it's not as unpredictable as it was before. I've got one time a day when I'm prone to lows, as opposed to three or four, and I'm now beginning to figure out what's really causing these lows (it's all activity level for me. If I get really busy after lunch I have to watch out) so I have a better idea at least of when it will happen.  |
