My migraine with aura has been pretty much gone for a few years now (with some leftover eyesight damage and the constant fear that it will return).
I've tried many things to cure it and I can't be sure what helped, if at all -- it could just be a coincidence and it would have gone away anyhow by itself or it might come back tomorrow -- however, I thought it might be worth a try for some of you.
Here it is in no specific order of importance from the top of my head and keep in mind above disclaimer:
1. It's personal, so we have to research and analyze for ourselves what fits our bodies. This is what I've done, basically applying analysis similar to "deliberate practice".
2. Aspirin. Seems to work really well. I took 100mg for several months. Then, if I thought it's coming I'd take 1000mg. That's the only thing I'm pretty sure about that actually works because the lightning zigzag lines just didn't show also no real headache.
2. I stopped 100% taking any anti-pain or anti-headache pills after reading about possible kickback that can make things worse. It's tough in the beginning but it does seem to reduce severity and frequency.
3. I religiously avoid any type of stress to my "head". The best way that I can explain it is if one goes to the toilet and pushes like they are constipated without breathing. This has to be avoided 100% and not be allowed to happen even once. When it did happen I was then on high alert for a migraine with the aspirin ready nearby or just taking a few pills as precaution. I noticed it happens when I'm on the toilet, having sex or getting angry. About the sex part, well, just take it easy and make sure you breathe. (this of course also applies to masturbation) Toilet time, never ever push and always remember to breathe. Getting angry, look up breathing meditation (it's simply a mind exercise and it works really well, concentrating on breathing) Also be careful with over-dosing on caffeine. I this this section is very important to the success as far as prevention
4. I'm avoiding sugars. No idea if it helps with the migraine but I feel better and lost weight without gaining it back. It's difficult in the first two weeks or so but then it's fine. Also no sugar alternatives.
5. I exercise. This has to be done carefully keeping no. 3 in mind at all times.
6. I take about 1mg of omega-3 each day. It has to be high dosage and from fish source as plant source has little absorption rate. Definitely has anti-inflammatory effect (I got chronic shoulder inflammation so I can tell) Also makes me calmer. No idea if it has direct impact on the migraine, it might.
That's it. Good luck!
