When I realized I'd be housebound and staying indoors to survive the constant paranoia I found ways to occupy my time. I discovered I could pace back and forth across the room I was in chain-smoking, and sipping on coffee. I'd do this for many hours of the day.
To make room in my stomach for all the coffee I was drinking I'd go out back where tall weeds would grow, and put my finger down my throat. I'd throw up what I just drank, making room for more so I could continue pacing. After a while, I didn't have to make myself throw up to keep drinking coffee.
This routine gave me a sense of pleasure, which was refreshing since the illness had removed pleasure from my life. Everything that previously gave me pleasure no longer did.
The routines of smoking, drinking, and pacing went on for years. I eventually grew out of the need to pace, and the high levels of physical discomfort left. I also quit smoking. I drink lots of fluids to this day, but I now drink as an aid to my spiritual life.
