Tonight at work I did a temporary basal rate. Dosed regular for supper then set up a temp. rate to run 20%less for the next 3 hours, finishing at 9:40pm. At 6:40pm my BG was 12.1. 9:30pm was 8.o and then 6.2 when I finished walking up the hill. Sweet! No crashing! Workdays I seem to manage great, and figuring out the temp. rate is really helpful.
