I completely second this. . . .

When I was younger, it was just a catalyst to amping the party up.

These days I'm more likely to do them alone than in a group, more likely to have a specific intention rather than just be seeking hedonistic pleasure, get a lot more (i.e. go deeper than ever before) on lower doses, . . . the list goes on and on.  It's amazing how much it has changed and for the better.  :d
