From what I've read, no 2 persons are alike. Please allow me to ask, why are you looking to find out how people self administer their insulin? If your system is working well with 3 injections per day, that should be sufficient. There's no too little or too much...it what's needed for your body/system.
All right here's the info you asked.
Newly diagnosed with T1 (Dec 2010) so I'm still following my endocrinologist's advise. So far so good!
NovoRapid b4 each meal and Levemir at 11pm.
Plus let's not forget that according to my endo I'm still in the HoneyMoon phase so this may all change in the weeks/months to come!
Good luck in your search and congratulations for having stabilized your sugar.
