For the last month or actually probably more, I am getting almost daily migraines

I am currently trying to get off narcotics(because i am addicted to codeine) and this is REALLY making it difficult! The vasodialator type of drugs like maxalt and imitrex are not an option for me, because I have issues with my heart. I REALLY dont want to go up in strength from codeine, because i am afraid ill just develop an addiction to that too. But i mean what can i do? They are one sided, changing sides every so often. I am taking a beta blocker and nortryptyline already, both are supposed to stop migraines.

I have a 15 month old son and im a single mom so its not like i can just retire to bed when i am in that much pain. I have to be up and mobile.
