My head was spinning 1st week back at work as completely new computer notes system had started whilst away. My tip...write a lot down and keep detailed list of work to do in diary form you can tick off. I found if overloaded I just couldn't remember things. The lists in my diary sorted that. Most I remember now..but I still use it. Lovely ticking it off as I go. I also put internal numbers, handy contacts etc in the back. (and computer help desk number with your IP address...for when the stupid thing crashes) I've still got 2 new thing to relearn...as it just got lost in my head those first few weeks back.. ..wished I written them down as not something I use a lot.
