Im ADD too.

Give your body time to adjust to the new food plan.

A brisk walk is a good thing. Both before meals and after a meal. One or the other is good enough. Puts glucose derived from the meal into the muscle cell, not into fat storage.

You are adjusting to a new schedule and woe, it takes time to develop a new normal. The nervous energy will calm down, at least it did for me.

Eating a fat snack filled the need to eat, and a cold drink. Sometimes flavored crushed ice eaten with a spoon fooled my body into thinking it was eating. Took about 10-15 min to consume 4 cups.

Hang in there.

Have you read Dr Amen's books??
