For me as the only developer at the company I work for it's either having to break creative (thinking) flow to switch to anything else that is expected or asked from me by my employer/colleagues, my own thought process wandering off due to unexpected hickups / issues I come across and have to fix first, or not remembering why or how I made something the way I did. On top of that it's also having to figure out my predecessors code descriptions.
