I do it regularly for a few reasons.
My clubbing circle has got smaller as the years pass, and nowadays the few events we agree to be all available for a go together are usually the big, mass-market parties. In other words, the ones I'm least bothered about!
This way I can pick my parties and I dont have to worry about keeping everybody happy.
I actually prefer it in a lot of ways. You dont have to sync toilet/fag/drink runs and you dont have to worry about anybody else not being on your level.
Plus, I find that I'm a lot more conscious and less likely to get too silly on the old intoxicants.
Or course, there are negatives too. The journey home can be especially lonely
