I've actually thought about that (spells draining the caster), too, 
but didn't think about it as a reason not to kill Lily.  
Interesting.  It would make sense.  However, it would also make sense 
that LV brought reinforcements and would have had some Deather Eaters 
with him, although I haven't read anything to support this.  The 
point being, he shouldn't have had to worry about draining his 
powers.  Part of me wants to say that LV would have been strong 
enought to perform three AK curses because he was just so dang evil.  
Probably would have barely winded him if whatever happened had not 
happened.

Which makes me wonder how it is we know at the beginning of SS that 
Voldemort's powers were deflected --  LV and Harry have been the only 
living witnesses, and Harry couldn't have told anyone.  Someone else 
must have been there.  My theory is that it was Snape and that he had 
something to do with the AK curse being deflected, but I digress.
