It's not only a financial burden but also very annoying because you never treat the cause but only a consequence. While you may fix one symptom, others may appear. Moreover the human body is complex and we have many systems that work synergistically, so it's always best to start fixing problems at the deepest level because higher level treatments will not be required then.
This is the biggest reason I am sick of treating symptoms. Thanks for articulating it better then I could!
Also, I'm sure there is a methylation block, but I am certain now that treating it directly isn't the only way this can be lifted. It's obviously int some of us it's more like a methylation supression than a self perpetuating block that must be lifted with supplements.
This is why people are having success with recovering using treatments not including the methylation treatment.
