I had a migraine with aura, nausea/vomiting, vertigo, etc. for all of October, most of November and December. On Dec 8th, I had orthopedic surgery and was out for 3 hours and on Propofol the entire time. I woke up with a completely clear head and NO migraine. 7 days later and NO migraine. I then did the research on Propofol. It is used occasionally in much smaller doses for emergency TX of retractable migraine. IT WORKS! Triptans and every prophylactic I have tried don't work or have positively unlivable side effects. The surgery cured my 2 month headache!!! I have had chronic migraines for 30 years. Get the word out! Ask your doctor.
