Wake me up!!

I just cannot believe how difficult has become for be to get up in the morning. For the last two days I have problems waking up earlier than 11.00 am. No matter when I slept the night before, when my alarm rings (and I usually set it for 9.00) I have a terrible headache, I cannot even open my eyes (not even mention getting up from bed (that is completely impossible),and generally I feel like a zombie. (Could somebody turn the lights on? Thank you!!).
Maybe I am just tired, or it is spring (well its not -20 anymore so that is a change), the only problem is that I have a lot of work to do (2 papers, one of them is my Masters research one) and being sleepy all the time does not help at all.
