There is a scene in the movie Trainspotting when Renton (Ewan McGregor) is coming off heroin. He locks himself into a room with: ice cream, milk of magnesia, water, a television set, Valium, porn magazines, and three buckets (one each for urine, feces, and vomit). He lines up the products on a table and proceeds to pull apart the boards he carefully nailed to the door so he can go out and have his last hit.
Gathering needed items for the first trimester of pregnancy is a lot like this scene. Minus the porn....and heroin.
high fiber cereal
access to treadmill
diet coke for my last hit
