Paying for Nurtec out of pocket

Well friends. This is how desperate I am. I unfortunately am uninsured until 3/1 and I have had a migraine almost every other day for at least a month. I’ve never been this miserable. I’ve already asked the doc for samples and only have one left of those. Question is: HOW do I get more? Is paying out of pocket my only option? And if so where is the best place to get them? Signed, feeing like a nurtec crackhead over here. 😵‍💫
