Excruciating migraine! help!?

Hello ive had migraines since i was 15 (im 28 now)and nothing seems to help or even take the edge off except for vicodin or norco and since i no longer have health insurance i don't take them anymore and cant afford to go and pay for a consultation with a doctor and yet alone pay for medication. I have tried everything over the counter that swears to relieve migraines and it does nothing for me. I guess my question is...does anyone know of a pill that can be bought (legally) over the counter that has the same potency as either vicodin or norco. Since like i mentioned earlier they help ALOT with my severe migraines, they don't go away completely but 90% of the pain is gone when i take them. Ive tried other alternatives to medication such as acupuncture, relaxation, aroma therapy, relaxing music...well you get my point. I understand that maybe i need to get seen by a specialist but while i save up money for one what can i do or try? thanks for reading
