I don't see libido as an addictive behavior. Well maybe when I was in my 20's.

I do know people that have given up drinking and drugs, or really slowed down their usage. Myself, we used to go out on friday nights and find a live music venue to party. That has almost stopped completely. I didn't connect it with Reta, but then again, the becoming more of homebodies did happen about the same time that I started Reta. The going out and partying was replaced with smoking some weed and getting naked much earlier in the night than after going out.
