From my personal experience programming (for my own pleasure) has three phases just like any other addiction. 1) Expectations phase where I love opening my laptop, touching the keyboard etc. and I have some sketchy ideas what to do. 2) Extatic phase - where I am working for 16-18 hours solving problems I didn't expected I would be able to solve and writing a code that I later keep re-reading just to appreciate it's dense beauty. 3) Diminishing returns phase where I am still trying to get some kicks from it but it isn't coming anymore. If you are in a phase 3 then it is clearly a time to stop, get sleep, do yoga, meditate, go for a run or get on a bike. Don't look at a laptop for a few days.
