Cafergot is an ergotamine abortive. Old school really. I took it the first time today and did not have the 'i cant breath side effect' so that is a good sign. Did well with the migraine which is good cause I needed a break from the T3s. It caused some nausea, but not so much when you take it with an anti-nausea med. In other words, good, cause I would like to maintain this plateau of health I have achieved and need a triptan to do that, preferably one that does not make me triple my asthma med to keep up with the breathing problems.
