Personally not sure about the diagnosis - limited nursing experience tells me that +++ Ketones at 11.00 am (GP surgery nurse) rarely turns into a trace by 13.30 (Diabetic nurse at hospital). Since then trace or nil.
From injecting 4 times a day - base plus rapid after meals - and eating my bodyweight in food to keep BG levels above 4 - now 14 units base only and 4-7.5 for 3 months.
Hence reckon a small dose is about right!
