totally agree, being a programmer is more than writin code. I have pulled a 90 hour week of writing code and it was very painful and I would never do it again.

I tend to pull an hour and then do something else unless I am in the zone and I can go up to about 3 hours and then break and come back to it.

8 hour days normally go like this when working with at clients place.

hour 1. opening up stuff, replying to email, grabbing a coffee, having a chat with co-workers(makes for a better working atosphere and you might learn something).

hour2. working on project, coding some, asking questions about the spec(if there is a spec, if not then asking questions that the end client or the account manager hadn't tought to ask)

hour3. repeat 2 but throw in a coffee and a chat and maybe a quick surf while you drink your coffee.

hour4. repeat 2

hour5. lunch time get up and move around people

hour6. repeat 2

hour7. repeat 3

hour8. start tying up loseends last coffee of the day etc send those emails you have been meaning to do, have a look at your bug list and fix a couple.

now you have done about 3 to 4 hours coding and plenty of other work.
