I read "it changed my life" so many times on internet, but from personal experiences and many friends I don't know anyone who'd noticeably changed their life for better.

Except for only one friend, who ended up suicidal and delusional beyond repair, frequent mental hospital dweller (although all doctors said drugs could only exacerbate a pre-existing condition, but not create it from scratch).

I wonder why so big discrepancy between internet and real life here.
