Help stop pregabalin without withdrawal.

I am currently taking pregabalin 75mg given for PTSD, I am very sensitive to it and struggling to quit it. Haven't started the process, long back tried tapering but started taking full dose. I am getting withdrawal like symptoms if I eat certain antioxidant rich foods like turmeric, garlic, amla, etc. This happens even if I try to apply herbal hair oil even rosemary. I doubt there might be some relation with underlying genetic issue that I already have. "Not sure whom should I visit first psychiatrist or neurologist" I will visit you in person. History: rarely occurring “hemiplegic migraine, involuntary neck & foot twist while walking(dystonia?) happens based on health. MRI normal & one side mild occipital lobe gliosis told but eye tests normal. Whole exome sequencing found nothing. Now my birthmark tingles found it’s(cafe au lait). I want improve my memory issues too. Long back PTSD cause head pressure feel resolves with ssri & benzo.
