I had a headache that seemed like a cluster headache and I took lsd every week for about 3 years, I'd get 5 days headache free out of 7 - was wonderful.

Then I met a gp who actually helped and mentioned indometacin and because that worked I was diagnosed with chronic parosysmal hemicrania.

PPIs didn't work, so I took ranitidine but eventually my stomach couldn't take the indometacin anymore and I had to stop it - the headaches returned.

Then I had an abcess in my jaw that almost killed me of sepsis and had to have two surgeries on my jaw and spent a month in the hospital on antibiotics. CPH didn't return.

Now I take a mild dose of propranolol daily and I rarely have headaches or migraines.
