I have no idea on the longitivity of it but the reason why i bring it up here is if and this was very rare over the last 20 years there was ever some relief it always felt like a band aid on a festering wound.
Like ok when i take this and do this and that maybe I get 4 hours of 10% relief send in the clowns you know.
All I can say is now it feels different.
But you grow to not get your hopes up anymore. So I am very hesitant to atribute any wonders here whatsoever none of that.
Also when you feel more normal there is no sence of exubirance. You just feel more normal.
Cheers.
