Hey Fleeman
Let me start by saying i'm so sorry for all the pain u'r experiencing. I have three girls about the same age diff's as u'r boys (14,11 and 9) and they are and have always been quite a handfull. I can't imagine dealing with ms and now migraines with three small boys. Kudos to u! I did some research on Rebif and it does seem that headaches are a possible side effect. Have u discussed this with u'r doc?? I don't have ms and can't answer u from experience of using one of the drug therapies, but i do have occular migraines and they are horrid. Has u'r doc mentioned Maxalt?? I've been using it for awhile and even tho i still get the migraines, i can usually take one or two of those pills and in about an hour i'm good! Sometimes of course they do not go away that easily, but overall it's been a miracle drug! The kind i use are the ones that melt on u'r tongue. There is another form, but my doc said this was the one which acted the quickest. Take care friend. Let us know how u'r doc proceeds with this and how u'r doing.
