things you can do with water bottle sleeves

Today I learned that you can get stainless steel water bottles at Ross Dress for Less for $3. Also, I have a waist pack for hiking that takes some finagling to securely hold a stainless steel water bottle, and today my husband figured out that this one kind of large beer bottle fits in the same way.

In getting-less-sick news, that thing where your body is supposed to handle bad stuff you inhale, and then you excrete it? My body is handling it now, but the end result is something I'm going to call garbage gut and leave it at that. My armpits hurt less now, so there's that.
