Puking is no fun. I've been there, in many situations. I've been slapped for the process, coddled, made to feel better, and verbally hung from the ceiling.
So, here are my thoughts and notes on caring for yourself, if you're alone, and have no sight.
The cleanup is going to be difficult at best and impossible without help at worst. If you've lost your lunch into the toilet flush, and make sure you've cleaned up any splatty bits.
If you've done so in a waste basket please take out the bag and double or even tripple bag it immediately. Hold your breath.
Wash your face with cool water. It helps you to feel better. The WU above gives excellent ideas, although I do have a few more that have worked for me.
Peppermint. If you're not allergic or it's not otherwise contraindicated for your case, use it. It should help. Of course if you're throwing up constantly for more than a few hours, you might want to call a doctor just to be sure.
