sounds like you are in biological sciences.
waiting for primers or cell lines? sounds like that.
it's mostly waiting, all the time, 30 mins here and overnight there.
try to use that time for something useful. 2 weeks is much better than 10 mins coz you can't do anything in 10 mins...
as already said enjoy the break, go and see your family... learn something new in that time. just don't sit and wait:)
