Jet lag is not my friend

Fortunately, I have plenty of friends here and have managed to settle back in pretty well.  I went out for some pintxos with one of my friends last night and then met some other friends at our weekly music night.  I left very, very early since I was totally exhausted.  I went back to my apartment and almost finished unpacking.    I fell asleep for a good two hours and then was wide, wide awake.  This is the worst part of jet lag for me - total exhaustion but the inability to sleep.  After years of fun times with insomnia, I have decent coping strategies.  I tend to get really stressed out staying in bed trying to make myself sleep, so I get up and walk around a little bit.  When I'm jet lagged (and not just normally struggling with insomnia) I also drink a ton of water every time I wake up, since I tend to be pretty dehydrated.  Unfortunately, lack of sleep and dehydration aren't my only jet lag issues.  I tend to also have stomach grossness (I'm never hungry and nothing tastes good) and I am usually really, really cold.  Apparently, body temperature also takes time to adjust with jet lag.  Add in the fact that it's been 65 degrees and rainy in San Sebastian, and I'm sitting in my office wearing to sweaters, long pants, and two pairs of socks.  I'm feeling totally unfocused, so I'm going to stop writing, grab lunch, and then head back to my apartment for a little nap.
