You can't do meth a couple days a week an everyone in your life not notice a difference in you. You can randomly have a binge or two a year and function well but as a weekly thing....no, being that you have access to it daily. Meth changes your sleeping , eating and thinking habits very quickly and it is not pretty. I know "Breaking Bad" is an Awesome show and it even partially shows how sick and depraved meth addicts get but the reality in meth users is far worse than you can imagine.
