seb, thats what i assumed. that some people just metabolise it differently and just coz i used to drink piles doesn't mean i still should.
lothar, yup , thanks for the tip about the chocolate. love chocolate.
high chance it could be that, housemate and i have a habit of late night chocolate. its not much, so i never thought of it. but maybe thats all it takes, because thats the one thing that HAS changed.
i went without coffee yesterday (trying to do assignments, lack of coffee, no fun.) but did have chocolate at about 10pm with the others and sleeping didn't happen.
then again, maybe its just a phase, like belgium said.
you guys are the best, so ubelievably wise and helpful!
