I generally work at home before lunch, then in a (cramped) group office after lunch. This way I get to work by myself for considerable chunks, get to do all my meals at home (good for budgeting), and still get to interact/collaborate with colleagues basically every day. Once I spent a full day at the office; I was totally beat afterwards. The only problem is that it _looks_ like I only work half-days to everybody else.
