YogaBuff,

Yes, I've had insomnia at times when I increase my workouts. Unlike you, though, I never expected the low-carbing to HELP. I believe (may lightening NOT strike me down) that heavy exercise combined with low-carbing is MORE stressful than exercise when you're carbed up. Why do you think the Cyclical Ketogenic Diet was INVENTED? As the weeks go by, I notice my workouts are definitely easier (both lifting and cardio) after days on which I've carbed up. Now, you can certainly adapt to exercise on a low-carb diet-- I don't want to discourage you. But if your insomnia is threatening to undo you, ease up on the workouts a bit before you get back into them again. If any expert (such as TrainerDan) wants to argue with this, I can respect another point of view--- I'm just telling you my experience.
