That drug can definitely make you feel funny, or well bad.. i haven't had a migraine in almost a decade, but used tried all of the triptans - none worked even a little, (would just do excedrin migraine and have to deal with it - vomiting and blind with the aura for 3-4 hours).. They can cause some tight chest pain, that flushed feeling etc... that was before I had any neuromuscular issues.. I always would drink caffine, as that helps the headaches.. and can help MG too! Good luck!
