I see what you're saying: I can't have just a little bit of sugar. I can't moderate. I've found I can't even have it in the house. I've got to purge it every bit as much as I had to dump alcohol down the drain when getting sober.
Others keep bringing it into the house. It has been relatively easy to keep my home alcohol-free, because everyone agreed my drunkenness was a problem; but nobody thinks my sugar problem is any big deal, so I'm on my own.
