I have 2 doctors that are friends of mine. One is a MD and 86. He is a great guy and very knowledgeable. The other is a pulmonary doctor and MD. He is saying he thinks it is sleep related. I had a c-pap but it went down and that's when things got worse. I have great relieve from Maxalt but now have had 4 in a row. All at night. Is it really possible to start a string of thee Migraines by taking it every time you have one?? What can I do the Maxalt works great but I don't want to take it if it is going to make me have them EVERY-NIGHT. !!
