donna, it's normal to feel kind of awful after a couple of days of induction! it's your body getting used to the reduced carbs. think of it as detox. it will last a couple of days, but it will go away. please eat something low carb whenever you want. don't worry about fat or calories. this bad feeling won't last! you'll be over it in a couple of days. i think it only lasted a day with me! you'll feel really great in a couple of days and as i said in another post, you'll have a renewed vigor, really!
have you cut out caffeine as well? caffeine withdrawal is day long headaches! it's really worth it though! you're getting over these addictions that you've had most of your life!
i sure hope you feel better soon donna!
