All right, now that you have decluttered your bathroom, it's time to get your first aid kit (or kits) organized.
Here's a handy page about building first aid kits for your home. (Sorry about the overbearing nationalistic imagery, folks).
Pull together all your various medical emergency supplies. See what you have already for the kit and start a shopping list for what you need to add.
You may find you have more than you need of some things (little bandages are a common culprit here), so separate things out and start kits for your office and/or car. Here's a guide to making a portable first aid kit.
Alternatively, buy a good kit from the Red Cross and, after you get it, donate all this jumble of stuff to your local shelter (except what you'll use to restock the kit for regular home use, e.g. bandaids in your favorite sizes).
