These were my first problem Sof-Sets.  I just use IV Prep on the 
skin, then use both pieces of tape over the set.  I once tried to put 
Tegaderm down first and insert through that but the needle/cannula 
didn't even pierce the tape!  Since I don't have many problems with a 
set peeling off or skin irritation I never put anything down first, 
just the wipe.  I sometimes have trouble with the tape, but that's 
just me.  If I manage to get it down without sticking it to itself 
it's fine.  If I end up wrinkling it then sometimes I need to use 
extra tape over the two that come with the set.

I also notice that when I remove a Silhouette I sometimes have more 
of a red bump than I ever did with the Quick-Sets or Sof-Sets.  They 
never really get infected, just more raised/red than the other 
sets.  I bought a box of those little circle/spot Band Aids and put 
one of those with a little antibiotic ointment over the red spot.

I've known my correction factor was off for awhile.  I meant to talk 
to my CDE about it in April but she made so many other changes that I 
decided to leave it alone for awhile.  I think maybe she suggested 
doing a square wave because I was dropping so quickly.  That might 
work but only if I also decreased the correction amount from what I 
was using before.  It is higher now (55 vs 45) and she did say to 
forget the square wave.

I plan on doing basal rate tests as soon as all of the requirements 
are in place - BG in range, no bolus or food for 4 hours.  Seems like 
whenever my BG is in the 100-150 range that Pumping Insulin 
recommends, I've eaten or bolused within 2 hours.  2 hours later my 
BG is completely different and I either have to eat or correct.
