Thanks Karen. I've been l/c for 5 weeks. Down 9 lbs. Since I cut the carbs to almost nothing, I've had the same symptoms. Drugged, headaches, muscles sore and tired, joints achey. What a mess. But, your description has given me new light. I'm not a meticulous carb counter. I have traded carbs for protein and have a 30 gram powder mix in the morning. I'm waiting for the new found strength.
