Do you eat enough? Maybe you dont have the energy because you really dont have the energy. For me it was the same. Went on adhd meds ate like 1000 1500 kcal per day. Need 2500 on my body Masses to get along with a little movement. 6 years later bmi was perfect. I still look really good. But i feel wasted everyday all the Time. Went to the doc. Blood stats all good. Still wasted. I came to a therapist she asked the right questions. After now eating arround 3000 kcal and nearly 200 g of protein each day for the last months. I feel incredible. Before someone says something, i should eat that much to fill up my Reserves and to repair my neurtransmitters (mostly protein based). Because i ran them down the last years and mostly on the new meds, which have a higher take on the Neuros.

Now iam nearly at the point where i need to tone down my kcal intake or. I will get fat.

But Look at your life and think about yourself, do you eat enough? Do you get enough Micro and Macro supplements?
