Time travel
After going to sleep around 2000, I woke up around 0200 and couldn’t get back to sleep for a couple hours. All this time travel thing gives me the creeps, so I prefer to stay awake only for short periods of time until I get used to the new epoch. This can take a couple of weeks, specially when the jump is big, like in this case, so this period is almost useless for working. Because I'm like a imsomniac vampire, wanting to go to bed but waking up anyways from time to time, I skip lunch time sleeping, breakfast craving for some sleep hours and dinner wishing I wasn't so stupid.
Then comes a period of raging activity, when I have to make up for the sleeping period. In this second period I don't watch too much for eating times, so I loose weight again.
I need vacations. If I don't have a copule of months without time traveling, I think I'll just vanish.
