I am thinking about changing my insulin from novorapid to humalog for the simple reason that i sometime can't remember if i have done my injection or not and if i was using humalog then i could have a pen called the humapen memoir which has a memory of the last 16 injections you gave and this would solve that problem. I would like to know if any one has changed from novorapid to humalog and if they have had any problems in doing so. I am also considering trying a pump for a trial period i have my meeting with my dsn soon and may enquire about that as well
