Has anyone else here been plagued with horrible headaches the next morning after you've had a non-LC sweet? My lovely MIL made a crustless pumpkin cheesecake she said was Low Carb...but after I ate it she told me it wasn't sugar free, but just low sugar... anyway, I was woken up by a massive headache about 4 am this morning. The only time I've been getting headache on this LC WOE is when I don't eat often enough and my blood sugar goes down. This morning it was a killer...like the migraines I used to have. I'm just wondering if it's the sugar, the drop in blood sugar, or a combo of both.
