Hi Guys, thanks for all the helpful posts, just come back from lunch, feeling little bit better, think I might finish a bit earlier today tho and have nap/walk. Actually normally go for a walk on my lunch break but yesterday and today been too knacked to do so Really cant sleep when I'm stressed, wish I could I'm actually more of a reader, fiction again, sadly not work ..scary the amount of books I've got thru in last few weeks in late night sessions... none useful for the PhD tho!
