Icing your upper neck and being disciplined to minimize poor posture and head movement can help. I need to use tri-focal lenses in my glasses. Tilting my head back to use the bottom lens causes problems. Falling asleep with my head tilted forward or to the left causes me problems too. I sleep on my back with my pillow curled around my head so my head does not tip to the side.

This injury does not usually have any pain. It may occasionally have a clicking feel. It can cause inflammation that restricts blood flow to part of the brain and it can cause muscle spasms, especially those muscles that attach behind the ears. Any soreness to touch behind the ears is a good indication of this injury.

What parts of the vitamins and supplements can you not take ? Is there a drug interaction issue ?

Maybe there are other ways to get your brain this good nutritional support.
