For some (like myself), insomnia can be a side effect of ketosis. I had trouble sleeping the first week or two of Atkins. It passes, I assume as our bodies adjust. I imagine stress can play a role too. Changing the way we eat is up there as one of the stressors in life.

Elaine, I have no idea why insomnia would strike several months into low-carbing. I doubt it's related directly to the diet, or it would have hit earlier, and been long gone by now. As you imply, maybe it has to do with a changing self-image - even good things can cause stress!

Hope it goes away and you're sleeping like a baby soon!

Actually, no, I take that back - babies don't sleep for very long at a time, and they wake up cranky....like a cat? a bear in winter? Well, you get my drift!
