I eat two meals a day at most, unless I have stuff that goes on all day (like a full day's surgery), in which case I require three meals. Generally though, I have a small breakfast and a huge lunch, which I just kind of digest until I go to sleep. Some days I don't even eat breakfast, just lunch. This habit led to one of my ex-girlfriends' nicknaming me "Camel," which I resented greatly.
I also only drink water, never juice or soda. I purify water and boil it every day so I have some to drink at any time. Though, this is also made up by the fact that I drink alcohol viciously at least once a month and kill my wallet in one night.
Why do you do this? Where do you live?
