Suffering from severe migraines

I am a sufferer of migraine for about 30 years and have tried numerous remedies. Recent blood tests have shown that my “Gamma GT is 223”.

Apparently, the reference range should be less than 60. I am a 53-year-old male, non-smoker.

Because of migraine I am constantly taking painkillers, paracetamol, etc., and am now worried that all this medication is causing problems elsewhere.
