The following is an e-mail which I received from a friend of a friend today.
The week has been very stressful. Exams every day, resulting in a lot of getting up before the sun and attempting to cram mountains of information in the brain before regurgitating it.
Went to sleep at about 12:00AM (midnight) on Friday night. Awoke five hours later (Saturday) to study and go to university for an exam.
Last night, got to sleep at around 11:00PM, after approximately eighteen hours awake.
8:40AM - Woke up with pulsating, very painful headache across entire head.
10:30AM - Got up, ate bowl of cereal and had some orange juice.
11:45AM - Took 500mg paracetamol with orange juice. Tablet split in half.
12:20PM - Took another 500mg paracetamol with water. Tablet whole.
2:10PM - Pain has not subsided and seems to be increasing slightly. Photophobia and phonophobia present: unable to listen to music or look outside due to sunlight. Ingested 0.3g dried Psilocybe cubensis (Cambodian strain) with a glass of water. Chewed for about thirty seconds before swallowing.
2:45PM - Pain has almost completely disappeared, as well as photophobia and phonophobia. No other effects apparent except mood lift and desire to perform air-drumming!
10:00PM - A relatively unproductive day but the pain and other symptoms have been entirely absent since about 3:00PM.
Preliminary conclusion: As a result of this experiment, the headaches suffered on a semi-regular basis as a result of irregular sleep patterns may indeed be migraines. Coincidence? Perhaps, but it seems unlikely as this kind of headache almost always lasts all day. Further tests will be carried out once this is experienced again.
