Temporary Basals

I'm not sure why, but I'm having major problems while at work.  In the afternoons and evenings I'm routinely going low (but only while at work).  So my DN recommended I try running some temp basals to try to deal with the problem.  I thought it would be a super easy fix.  I actually started with a higher temp basal than I thought I would need (I subtracted 15% from my afternoon basals starting one hour before going to work) thinking that would be a bit too much.  It wasn't.  That day I still went low (and I worked 12-4, 5-8, and managed to go low both in the afternoon and evening with the temp basal).  So I tried subtracting 20% the next day.  Once again I still went low (that was just in the afternoon.  While I haven't solved the problem at all, I at least got some really good info.  It looks like I go low later in the afternoon, so I don't really have to start the temp basal as early as I was (in the afternoons, which is where I have the most data, it looks like I can get away with starting the temp basal at either 2pm or 3pm instead of 12pm like I was - I go low after 3pm by the looks of it).  I'm not positive, but I'm thinking I can do the same thing in the evening, too (start it at 5 or 6pm).  I'll have to do some more testing to find out for sure though. 

Of course this week I've been mainly working mornings, when I have no problems with this whatsoever; I'll have to wait until the weekend to try a minus 25% basal in the afternoon.  I'm working tomorrow evening though, so I'll see how the evening goes!

Oh yeah, I did a basal test during an afternoon where I wasn't working.  And I didn't see this glucose drop at all.  So it definitely looks like it's because of work!
