thanks for all the tips. i really think its just a case of resetting my body clock again. Maybe this weekend, i'll go on a bit of a bender and hit the whiskey ! I had a cup of hot cocoa last night, didn't help, actually just made me wake up for a whizz at 2am.. and then like frickin clockwork, up at 4am again.. could have saved myself the 300cals there by not bothering.
