I was feeling pretty tired and woozy around 3 p.m., about an hour after my snack of walnuts. I came home and had 1/2 a large fuji apple, ran for 35 minutes (it was really hard - am I already glycogen depleted after 2 days?) and walked for a little bit too, and then had the second 1/2 of an apple. I eyed some protein in the fridge but it did not sound appealing at all. I had a swig of milk later while cooking because I wasn't feeling well - woozy again. Perhaps it's just carb withdrawal?
Just had my dinner and I feel fine but sheesh. I'm going to work on morning workouts. It fits best for my schedule and I bet I would feel better.
