Instinct? Experience? Don't know. Bad BGs? Perhaps you can't spot it, 
which is why they just say change every 2-3 days?

I was pondering my forgotten injection while in hospital yesterday. 
They did the MRI last Friday. This was a SPECT (they were using 
Thallium 201, Nanette). I had to lie totally still for 30 minutes, 
and surprisingly I didn't fall asleep like I normally do :-) Re the 
forgotten injection, I realised I always - yes, always - check my BG 
before I eat. It tells me how much to bolus. So, take away the 
testing (my meter was broken), that was how I forgot to bolus - the 
usual sequence of events didn't follow through. Good to know there 
was some logic there after all!

It is reputed (is it in the Bernstein book? I forget...) that several 
small injections will give you better absorption than one big 
injection. Better as in faster, more regular each day, that sort of 
thing. I think Bernstein says never more than 7 units in an 
injection. If you have needle-phobia, that can be a tough choice. But 
if you're easy about injections (like me) and have to inject (say) 20 
units of Insulatard, you might do 3 injections: 7, 7 and 6. You might 
fill the syringe once, and put about a third in 3 spots across your 
stomach. On the pump, I personally never bolus more than 4 units of 
Humalog in one go. If I need more, I'll wait 30 minutes before 
bolussing any more. If I'm bringing down a very high BG, I might 
bolus some (to keep the infusion set working!) and inject some 
elsewhere. Seems to work OK.
