woke up from another cluster headache

at 2:10, i wake up, mild headache. holy fuck then it got worse. i felt like i was being my ass kicked. my god it was painful. lasted until 2:50, then the after shocks were still kicking it till about 2:55. now it's calming down and almost 3 am. it could've been sinus this time cuz my nose is tripping, but i think i didn't drink enough water the whole day. i only drank one mug instead of 2. that's very little. will have to drink 2 per day minimum. i just got behind with my user having problem at work. my own fault.
