My neuro diagnosed me with CH with a rare variety where I also get a migraine. This was when I initially had them 4 years ago.
I have never had a migraine other than during the attacks, but most of the time the migraine lasts for hours after the CH ends.
The CH have definitely changed. At first they lasted about 2-3 hours at 2pm and sometimes also 2am daily. Now they only last around 15-30mins, but I get between 1-4 attacks daily, usually at either 2am, 4am, 6am, 8am, but occasionally at other times such as 9pm.
I tried busting with Psilocybe semilanceata on Monday
