Thank you very much for sharing your story!

Perhaps the following information would be valuable for you:
1.) Check if your atlas (C1) is in the correct position, see http://www.atlantotec.com/en
Please do not underestimate this, this might be the main reason. This can be made visible on a CT. If your atlas was misaligned at birth, which happens often because women are forced into a highly unnatural birth posture by the birth chair, which reduces the birth canal by 20 - 30% (this was measured, see http://www.naturesplatform.com), which forces doctors to use suction cups etc., which often misalignes the atlas for life, and you later had a whiplash accident or any trauma involving the neck, then the atlas shifts even more and the results are "suboptimal", like rollercoaster vertigo ride suboptimal, you get the idea. A misaligned atlas puts constant pressure on brain and spinal nerves, and inhibits blood flow in the neck (which is also associated with migraine). You dont need to have a whiplash accident later on btw to experience the full range of symptoms (the list of ailments associated with a misaligned atlas is VERY long), it all depends on the graveness of the misalignment you suffered at birth.
I consider 1.) to be the most important point.

2.) Incline your bed see http://www.inclinedbedtherapy.com
This optimizes blood flow and basically everything inside the body, including the flow of the cerebrospinal fluid.

3.) Try the so called "Natural Sleep" http://www.naturschlaf.com

4.) Take HIGH DOSAGE Vitamine C (see Dr. Levys books), HIGH DOSAGE Vitamine D (see Amazon, books about Vitamine D, always combine Vitamine D with K2), and HIGH DOSAGE lugols solution combined with selenium (see the article about Iodine at a magazine called "NEXUS", or see for example the user "Fenbenlady" at minds.com and her group about Iodine.

There are many more tips I could write you, but it would all be speculation, like heavy metal poisoning, focal infections (like root filled teeth), too much exposure to technical radiation (cellphones, WLAN, cellphone towers, DECT etc. etc. etc.), too much glutamate etc. etc.. Just dont expect doctors to play Sherlock Holmes, they wont and they dont, all they do is symptom treatment, as this makes the most profit, and this includes surgeries, which make an even higher profit. I hope you realize this, I suggest you better do before they f*ck you up for life.
