Net lag

Traditionally this term refers to the delay that occurs when a large amount of users are "on" the information superhighway, or when a dirty connection slows down the retrieval of data from a server.

Like many good Internet terms, its meaning has morphed to describe the unfortunate physical side-effects of being online for an extended period of time. According to The Chronicle of Higher Education, "the condition resembles jetlag, but can also entail eye and muscle strain". You knew there had to be a word for it!
