The bottom line about any social is they are hard work. I was unavailable to see clients for three days in the beginning, but after a time it was so stream lined that I only took two days off: the day of and the day afterwards. I always lost a few pounds though because the party itself is non-stop work. I felt it was good for overall marketing for me, but the parties themselves never did anything but cost me money.
If anyone is interested in starting up a social PM me. I'd be glad to help you get started.
