Things to help relieve a headache/migraine?

I have had one continuous headache/migraine for the past 5 months from a severe concussion i got. I cant remember what it feels like not to have a headache.I have tried many migraine meds such as maxalt, ive tried diamox to relieve the pressure in my head, and other meds... None worked:/ the diamox helped a little but i still had the headache and i couldnt get any sleep so i had to discontinue it. All this pain i go through everyday has caused depression for me and im tired of the s.H. !. T i get everyday from people who dont know what i go through. Everyday im so dizzy and light headed i feel like im gonna pass out, or throw up. I have thrown up a couple of times from being so dizzy and having such a bad migraine. Ive also tried tylenol, motrin, advil, ibeprofen, dosent help at all. I dont see any doctors for a while. Are there any other things to help relieve a headache/migriane?
