I’ve been trying to keep it low in carbs bc I’m gaining weigh too fast and it’s just because of that. Also because my I passed my glucose test for one point. But tonight im feeling terrible, I started feeling hungry then shaking and dizzy and super weak. I’m sleepy I wanted to fall asleep but couldn’t, I was so uncomfortable I cried. I asked my husband to get up and make me some ham and cheese wrap before I fainted or vomited. I think it might be because of the low carb diet and I won’t keep it up. I won’t eat them excessively but I’m not feeling ok. It’s so frustrating that they make me fat so easily.
