Karen,
Do you have any thoughts on why it might have made you feel groggy?
i'm going through the steps on the web site and it seems pretty interesting
(though there is no way i could go back to having the carbs she mentions
in the first few steps)

i found this interesting:
If you find that you are having wild dreams on the nights you have your potato, this is a clue that you have low serotonin. This means you are getting a bigger hit of serotonin than you want right yet. The bigger hit means your levels are very low. You need the serotonin, but it is better to go more slowly. Ease into it and let your brain catch up. Have a smaller potato, or eat just a half or even a third of it. Your body is talking to you. Listen.

Soon after i began to limit my carbs I was having bad muscle cramps but couldn't afford the potassium at the time. i still had some bananas here and i ate one of those on two different nights. i ate them soon before bed because i figured if they did cause an insulin spike i would be asleep so wouldn't have the cravings. Anyway both of those nights i had very wild(and disturbing dreams) like i had never had before. i even mentioned it back then in my journal. i am wondering now if there was some connection...
