When I got it I was 7 months pregnant. For about 8 hours I sprawled on the disgusting basement hallway floor outside our disgusting basement bathroom (so that I would not wake up my DH), alternately getting up to vomit and cr*p every hour. I didn't even care. I could have been laying in the middle of the street and not cared. I have never been so sick.
It took a couple of weeks to really feel myself again.
