Amitriptyline
"First started taking for cluster headaches (much worse than your run of the mill migraine), worked a treat. Was taking rizapan, sumagram, maxalt, basically all the Triptans and while they work I get about 4 cluster headaches a day so I started to get headaches from the overdosing on Triptans. Went to hospital and endone did nothing for me. Tried beta blockers, they made me really sick. Even did physio and acupuncture, don't even bother.... 30mg of endep and the cluster headaches are completely gone."
