From personal experience of having done it almost weekly for a long stretch (multiple years), and then quitting cold turkey, it took me a few months to fully land back in reality, but I've since had a successful career as a software developer, with a happy and healthy family life, and that's typical of the people who I knew back them that I've kept in touch with.

Whatever the serotonin generation issues are (and I definitely had them, and that's why I stopped taking it), they seem to recover over time.
