If you don't know the Instructables site, you should. Here you can find directions for making a near-unbelievable array of stuff. And if you aren't up for actually making something, Instructables is perfect for your fantasy life: you can dream dream dream about how organized you'd be, how productive, how domestically thrifty, if you only had the time.....

And, speaking of time, just in time for holiday overindulgence Instructables brings you DIY imitation Alka-Seltzer. I gotta say I'd probably be willing to pay the 50 cents per dose for the Real Thing--or look for a sale--rather than launch a domestic chem lab. But perhaps you didn't have an, um, explosively messy experience in high-school chemistry. I did, and it cured me of any impulse toward amateur alchemy.

If you decide to tackle making this literal home remedy, it's probably not a good idea to wait until you're actually hungover.
