So update time, the cold is finally --
finally! -- gone and I can vape normally again!

In other good news, a buddy of mine brought over some MBV juice (Cafe Coffee, 36mg, 80/20 "house blend") and I'm fairly certain that it wasn't the PG in Halo juices that I'm sensitive to, as even Mt. Baker's 80/20 is thicker (therefore probably higher VG percentage) than Halo's, and it wasn't more inhale-able than the Halo juices I've got.
Incidentally, that leads me to believe that Halo's juices are probably close to 100% PG.
