Lying pretty well goes along with a history of drinking problems, so no surprise there, and nobody likes lying much either, so again no surprise. Yeah, people often do relapse when quitting, so again no big surprise. And yeah, people do lose faith in us when we in the past quit over and over again, and consequences for our past drinking follow us around for some time goes without saying.
Relapsing is not inevitable, and so many choices made now can absolutely keep you clean and sober without relapsing ever again.
The opportunities for keeping sober are there for the taking, and if you already have 19 days in, your more then ready to embrace the ideals of discovering for yourself how to believe enough in yourself to ensure your sober success!
Give yourself a break. Give yourself a chance to do right for YOU. It is more difficult when somebody you love has doubts, yeah, but nonetheless, YOU are in charge of YOU, so make the best lemonade you can when things are sometimes going sideways - life will get better even if at first it doesn't seem so. Quitting drinking and changing up our lifestyle really does work!
