6 years ago i used to do it to a degree, but at that time i was on old pork insulin, around 1530hrs the long acting would take dip, at this time i would have a 2 hour work out (4 times a week) this then also lowered my sugars and i was then able to have a good tea, though protien heavy and would use high protien drinks, sugers used to be fine.
now i'm old and on lantus
