Headache and a bit of nausea which got worse as the day progressed. I'm pretty sure that it's my fault for continuing to use the Earth Balance spread which I left out all day, about a week ago.
I made it home on the metro/bus without throwing up. If it weren't for the plastic bag that I found on the red line train I might have lost it then and there. Having that bag gave me an escape valve in case I couldn't make it.
At home, after a short bout of self-induced upchucking, I had a little bit of matzah and then went straight to bed.
