just documenting this for my own records. woke up at 6:40am with a cluster headaches. started going away 20 mins later at 7am. it's still pulsating, though. I been having real little sleep since I got sick and my nose always is stuffed. I feel like the mucus that drains causes this headache. I had mild headaches all day yesterday, and they got slightly worse at night. but this morning it fucked me up. I still feel it, but it goes on and off periodically. cluster headaches suck!!!
