No problems. I have very erratic blood sugars with frequent hypos and hypers (often 2s then 28s!) and i seem to be quite sensitive to changes in my insulin, particularly my lantus. Even altering it 1 unit will guarantee a hypo. Also my food ratio (1.5:1) is very infexible, particularly at lunch. This is now affecting me at work as im either very high at this ratio and falling asleep at my desk, low concentration etc or i hypo if i increase it.
The hospital gave me the option of splitting my lantus, but as i find it very restrictive and extremely painful i wasnt happy with this. So the pump was mentioned.
I seem to have very clear parts of the day when my lantus is not enough (ie. dawn phenomenon happens to me at about 10am!) and then the post lunch highs. So the flexible basal rates should go a long way to combat these. and as for the hypos, i currently get to the point where i cant move or speak (during the night) and need assistance from a member of my family to get out of it. Although luckily my hypo awareness is pretty good when im awake!! so get better control should make a huge difference to my life.
Thats a very brief overview!!
