I sit at an L shaped desk for my breathing (does everyone call vest and nebs breathing or is it just my family?) that way I can use the computer while breathing. On my left hand is a wide night stand that sits under the desktop with doors on the bottom and a pull out drawer. Behind the doors of the nightstand my vest and pump sit. In the drawer I keep 1-2 weeks of tobi, albuterol, and hyper-sal in small-ish boxes (along with some thumb drives and usb cords). I also have 4 'active' nebs that sit in a microwave safe container (when clean) or just outside the container (when dirty), that fits in the pull out drawer. I have 4 sets of nebs (2 morning, 2 night) so I clean/sterilize them before my night-time treatment. The desk has a medium sized door where I store months’ worth of the inhaler meds (except the fridge stuff) and spare nebs, and hoses.
Single bottles of enzymes, azith, and supplements go in the kitchen next to cereal bowls (so I don't forget). The big box of enzymes goes in a box in the pantry. It stays pretty organize, but I tend to leave out dirty nebs or my vest and hoses unless company is coming over.
I thought about building me a special furniture piece for the breathing stuff, but eventually just repurposed the night stand after finding the desk at a yard sale.
