The question is inadequate. To answer this type of question more information is required.
What method will this cure utilize? What degree of success will it have? Will there be side effects or potential for undesired effects? What will those be and what further methods can be used to minimize them? What specifically are you curing? AS presents in individuals with variation, how will this cure interact with variations in conditions? What are the costs, even if free to the taker, of the cure? Which government agency is offering this cure and how accurate are their claims? What is their intent?
There is more, potentially much more one could consider in asking themselves if they want a cure or not.
Personally, I would answer the original question with a firm "No". There exists a few potential situations wherein I would answer "yes", however. And similarly some situations I would answer "I would try it".
In principal though, I am strongly against anything that fundamentally undermines ones sense of self. Each of us is unique, and as a species we are all the better for that very variation. We each have unique experiences, troubles, joys, every facet of existence is beautiful and miraculous.
I find it odd for a triangle to want to fit through a square hole, and troubling when someone attempts to force it in. Even if someone succeeds at smashing it through, you have not cured the triangle into being a square...you've simply smashed it, and the triangle is gone.
