I love them. I'm not sure if I plan on taking them "for life", but they're one drug that I never don't have with me, in some supply or another (sometimes it's Xanax, sometimes it's Klonopin, sometimes it's Valium, etc.) The only other drug I never am without is cannabis, and sometimes this fact has given me pause, like "am I addicted to benzodiazepines?" Maybe. Probably. But I've been able to maintain my usage on a "as needed" basis for years and have never strayed into physical dependency, so I'm not particularly worried about it from that perspective. Have they crippled my ability to interact socially sans-benzos? In all honesty I don't think they have. My social skills have gotten better since I started taking them but I think that's due more to taking psychedelic drugs & just forcing myself to be in social situations and get outside my comfort zone, I don't think it has much to do with benzodiazepines.
I don't know, I just really like the feeling of the drug starting to work it's way into my bloodstream...it's not a "rush" or anything like what most drug users are looking for, but for me it really hits the spot so to speak.
