Holy shit. I spent the whole day in bed. It started last night. I couldn't sleep and tossed & turned till around 7 in the morning, when I finally was able to pass out. I woke up a few hours later feeling really tired, with a headache, and upset stomach so I slept some more. I woke up feeling the same. Then I went back to bed and repeated the process. It's now 1:00 AM and I feel a tiny bit better but far from 100%. I hope tomorrow is better. I've never felt like this before, if it doesn't go away I might go to the doctor or ER. This sucks!
