That’s not addiction. Addiction is just as much psychological as it is physiological, and goes way deeper than chemical dependence. Once you’re through the withdrawals of SSRI dependence you’re pretty much good, while an addict will most likely struggle for the rest of their life.
I definitely don't suggest it. It's an interesting experience if you're unemployed and just sitting around doing nothing. But if you have responsibilities and work to do? Hoo boy does it suck ass to move around with it.
