Is It Safe To Take L-tyrosine For Dopamine Deficiency Leading To Headaches?

I think I may have a dopamine deficiency. I m taking L-tyrosine at 500 mg once a day to start & eating foods high in dopamine. I will up my dosage to 2-3x a day, just taking it slow bec I ve heard about side effects. My question is this- I read that if you start getting headaches from it that means you don t need it anymore. Is that true? Will your body then, be able to produce the normal amount on a consistent basis? Thanks
