Woke up with a bad headache and feeling very week - slightly dizzy. Had my lunch box, fruit and even milk for my coffee packed before I went to bed, but it didn't seem like I'd be able to survive the day in office. Texted my maanger saying I'm not feeling well enough to go to office today, and went back to bed, hoping I'd be better after a nap. Woke up at 3pm! The headache was different, and I tried getting as much liquids in as I could, as I thought it could be a combination of dehydration and not having eaten anything since last night. Didn't feel much better till maybe 6 or 7pm. Took the lights off the Christmas tree and the stairs, logged in to submit some work so that others could pick it up next week in case I countinued to be unwell. Was feeling better so decided not to cancel my weekend sailing trip, although I was nervous given the weather was predicted to drop below 0 on Saturday night. Packed my bags and in what seemed like slow motion - in hindsight, it really felt like I was still not fully functioning.
